How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
The lot specific COA document can be found by entering the lot number above under the "Documents" section.

Large RNAs (18S and 28S) from the pellet fraction can be purified after transferring the microRNA-containing supernatant to a new tube by using the total RNA protocol or by phenol/chloroform extraction.
We have used to the kit to purify in vitro transcribed small RNAs with great success, but have not done so with purified total RNA. Here are the steps we would recommend trying with purified total RNA:1. Prepare a lysis mix with 0.7 vol. Small RNA Lysis Buffer (M1070) and 0.3 vol. Binding Solution (L8042).2. Add 500 ul of lysis mix with 50 ul total RNA and mix thoroughly.3. Spin at 14000 rpm for 5 min to precipitate large RNA.5. Transfer the supernatant to a new tube.6. Add 610 ul (1.1 vol.) 100% ethanol to the supernatant and mix well.7.Transfer the mixture to a binding column and spin 1 min to bind. Repeat the binding step with the remaining mixture.8. Wash the column first with 700 ul 100% ethanol, and then with ethanol-diluted wash Solution 2.9. Dry the column and elute small RNA.
We have not tested mirPremier™ microRNA Isolation Kit with sperm cells.
Too much residual medium or cell mass may lead to recovery of some large RNAs. It is critical to remove as much residual medium as possible by re-centrifuging the pellet. One can also test different ratios of the lysis mix (Small RNA Lysis Buffer and Binding Solution).
