Gently pipette to mix thoroughly. 2. Poly(A) tailing reaction: Incubate at 37°C for 30–60 min. 3. Reaction termination: Immediately store at –20°C after completion, or add EDTA to a final concentration of 10 mM, or perform phenol/chloroform extraction followed by ammonium salt/ethanol precipitation of RNA.

Guidelines

1. Due to the involvement of RNA manipulation, strict adherence to RNA operation protocols is required to avoid RNase contamination. Related reagents and consumables must be treated with DEPC to remove RNase or ensured to be RNase-free. 2. The RNA used for the tailing reaction should be appropriately purified before use and dissolved in RNase-free dH2O. The solution should not contain EDTA or salts. 3. If it is difficult to ensure a strictly RNase-free environment, it is recommended to add an appropriate amount of RNase Inhibitor to the reaction system to enhance the stability of RNA in the solution. 4. During experimental operations, enzyme products should be kept on ice at all times and stored at -20°C immediately after the experiment.

Runs small. Order up a size.
Color: Black (001)/Jet Gray, Size: Small
I have small hands so I ordered a small. I even measured my hands to make sure. I couldn't even get the gloves on. They are cute though. They don't seem great for the snow, but I couldn't get them on to even try them out.

great cold weather wardrobe addition!
Color: (110) Summit White / Summit White / Khaki Base, Size: 1 Count (Pack of 1)
So glad I got this. Got tired of trying to manage hats and ponytails in the Northeastern winter! Super well-made, very warm and soft, and so cute!!! I'm a sucker for a beige cable anything. sometimes I stick it around my neck too when I'm not feeling-scarf-y, and while it's not full coverage, I'm glad to have it.

Perfect everyday bag for men
Size: One Size Fits Most, Color: (025) Castlerock / Black / Black
It’s lightweight, attractive, and the perfect size for carrying the amount of things you want throughout the day. Can be casual or carried into a fine restaurant. The strap is long enough to wear cross body on a large man. Also, they provide a loop that allows you to fold up the strap and turn it into a short handled bag. Great price for the quality and usefulness.
