Genohubs ngs search interface. Once youve narrowed down the"tion youd like to move forward with, your project is confirmed and pdf detailed shipping instructions and conditions are displayed. Shipping to the United States, shipments from around the world to the United States frequently arrive without any issue or hold up at customs. A small percentage of shipments do get held. To reduce this chance even further, include the following letter in your shipping documents both inside and outside the shipping container: Contents of this package are non-Infectious, non-hazardous, not an etilogic agent, not for human consumption. Shipment consists of sterile dna for scientific analysis only. The material contains small pieces of genomic dna suspended in sterile water. The material was not generated by microbial fermentation. The product is purified and does not contain animal or cell derived materials or additives.
Label the box as temperature sensitive, keep frozen. Send the service provider a tracking number so they know when to expect your package. For international shipping, attempt to ship on Monday or tuesday to avoid delay associated with delivering on a weekend. Determine whether the country you are shipping to has a holiday. Shipping during a holiday can needlessly delay the time it takes for a service provider to unpack and properly store your samples. Using these recommendations writing will completely ensure youre properly shipping raw, extracted nucleic acid, tissue or libraries. If youre looking to find and compare sequencing and library preparation"s between service providers, use.
Shipments between Asia and North America. Shipments between south and North America. In a thermostable box where the Styrofoam is at least.5 inches thick, 3-4 kg of dry ice should last for at least 48 hours. Use the fastest available courier,. FedEx, ups, dhl or usps. The carrier may ask that you fill out a commercial invoice. Label your contents as non-hazardous research sample.

A constructed library is a very stable, double stranded pcr product. Most providers will want between 2 10 nM of that library for sequencing. If youre shipping a library youve constructed yourself, reconstitute your library in 10-50 µl of 10 mM Tris.0 buffer and use microcentrfuge tubes that are 'low-bind'. At very low concentrations, libraries writer tend to stick to tube walls. Our recommendations for shipping constructed libraries are the same ones as shipping dna samples. Packing and Shipping, place your dna or rna sample in.5 or 2 mL screw walk cap microcentrifuge tube and seal with Parafilm. Pack the tube in a freezer box, 50 mL conical vial or some other method to protect it from breaking.
Place into a thermo-stable shipping box. We recommend the Styrofoam be at least.5 inches thick. Fill the box with dry ice or wet ice. See rna or dna sections in this guide to determine whether dry ice or wet ice is recommended. Here are our rough recommendations for the quantity of ice to pack: Shipments within your continent:. Shipments between Europe and North America:.
If youre only using.1 mm edta, by the time your concentrated dna is diluted, and then diluted again during the first step of library preparation, the concentration of edta is so low, there is no chance its going to have any effect on the. If after this, youre still worried, just reconstitute your dna in 10 mM Tris.0 rather than. Yes, you can probably get away with shipping a pure dna sample in water at ambient temperature. You can also lyophilize your dna or dry it down on paper, but make the life of your service provider easier and just ship on a wet ice pack. You can ship extracted dna on dry ice, but there is no good reason for this. Shipping Fresh Tissue, fresh tissue should be snap frozen and shipped on dry ice.
If youd like a provider to extract rna or dna from this tissue or if you cant ship on dry ice, a preservation solution is recommended,. Rnalater or dna/rna shield. These are aqueous solutions composed of ammonium sulfate that co-precipitate rna and cellular proteins, 1) rendering rna physically inaccessible to nucleases, and 2) inhibiting nucleases. Ammonium sulfate precipitation is typically a method used for purifying proteins by altering their solubility. Protein solubility depends on the ionic strength of the solution. At low ionic strength, solubility of protein increases with increasing salt, at high ionic strength, protein is completely precipitated out of solution, also known as salting-out. There are a few online protocols for making your own ammonium sulfate based precipitation solution. Here is an example protocol from Palumbi lab at Stanford University. Commercial or homemade rna preservation will preserve rna for up to 1 week at room temperature or 4 weeks at 4c, allowing processing and shipping of samples without liquid nitrogen or dry ice.

See the packing section below and follow instructions for shipping with dry ice. Ethanol Precipitation, re-suspend your total rna in a 100 ul precipitate solution. Add: 1/10th volume of 3m naoac,.2 3 dissertation volumes of 100 ethanol. Mix well by vortex. Follow packing instructions below, but instead of dry ice use wet ice packs to maintain a -20 to 4C shipping temperature. Shipping dna samples, shipping dna that has been dissolved or re-constituted in te (10 mM Tris, pH 8,.1 mm edta) or 10 mM Tris.0 with 4C wet ice packs (blue ice) is the recommended way to ship dna samples to a service. Some service providers worry about the edta in te inhibiting enzymatic reactions during library prep.
If your sample is contaminated with nucleases, youll need to slow down the rate it chops your rna by reducing essay temperature. Finally, remember that rna can be fragmented in water with divalent cations and heat, so heating rna in water is not a good idea either. See our recommendations for shipping rna in dry ice (recommended) or an ethanol precipitate if you cant ship with dry ice. Dry Ice, for most rna applications, youll need to ship total rna. If youre interested in small rna species, dont forget to use a method that preserves small rnas. Clean the surface of all tubes and use nuclease-free tips. Use nuclease-free water for buffer preparation and reconstitution of your total rna sample.
and shipping solution to ship extracted nucleic acid sample or library. What you tend to hear from each lab manager can vary, so we decided to put together a unified standard. With over 100 service providers offering library preparation and sequencing services on Genohub shipping recommendations were diverse, but going through each one of these weve put together a set of best practices. If youre ordering a sequencing service. Genohub or even from a provider outside of Genohubs network, you can follow these guidelines and rest assured that your samples will have been prepared and shipped properly. Shipping rna samples, dry ice is by far the easiest and most recommended way to ship total rna samples. If you cant ship with dry ice an ethanol precipitate is also fine. If you have an absolutely pure total rna sample you can probably ship at room temperature or leave the sample on your bench for 1 week. However the reality is that many preparations and isolations do not completely remove nucleases.
In other words, you are looking at the molecule from a bit above the plane of the ring. Deoxyribose, as the name might suggest, is ribose which has lost an oxygen atom - "de-oxy". The only other thing you need to know about deoxyribose (or ribose, for that matter) is how the carbon atoms in advantages the ring are numbered. The carbon atom to the right of the oxygen as we have drawn the ring is given the number 1, and then you work around to the carbon on the ch2OH side group which is number. You will notice that each of the numbers has a small dash by it - 3' or 5 for example. If you just had ribose or deoxyribose on its own, that wouldn't be necessary, but in dna and rna these sugars are attached to other ring compounds. The carbons in the sugars are given the little dashes so that they can be distinguished from any numbers given to atoms in the other rings. You read 3' or 5' as "3-prime" or "5-prime". Attaching a phosphate group, the other repeating part of the dna backbone is a phosphate group.
Dna, on, nanotubes Offers
The sugars in the backbone, the backbone of dna is based on a repeated pattern of a sugar group and a phosphate group. The full name of dna, deoxyribonucleic acid, gives you the name of the sugar present - deoxyribose. Deoxyribose is a modified form of another sugar called business ribose. I'm going to give you the structure of that first, because you will need it later anyway. Ribose is the sugar in the backbone of rna, ribonucleic acid. This diagram misses out the carbon atoms in the ring for clarity. Each of the four corners where there isn't an atom shown has a carbon atom. The heavier lines are coming out of the screen or paper towards you.
