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.
For the lysis procedure, use a freshly prepared solution of 500,000 units/ml in 10 mM Tris-HCl, pH 8.0. The product is also soluble in water (10 mg/ml) yielding a clear to slightly hazy colorless solution. Aqueous solutions should be stable for at least one month when stored between 2-8 °C.
Solutions of Lysozyme may be inactivated by boiling for 40 seconds at 100°C at an alkaline pH.
Lysozyme is a single chain polypeptide of 129 amino acids. The amino acid sequence of chicken egg white Lysozyme is described in the Journal of Biological Chemistry, 238, 2698-2707 (1963).
The following procedure is for the lysis of E. coli. It may be used as a guideline for other species.1. Incubate E. coli (strain ATCC 37017) bearing the pBR322 plasmid overnight in Terrific Broth (Product No. T 0918) with 25 μg/ml tetracycline (Product No T 3383) and 25 μg/ml ampicillin (Product No. A 9518).2. Centrifuge 1-2 ml samples of the overnight culture.3. Resuspend the pellets in 350 μl of STET buffer (10 mM Tris-HCl, pH 8.0, with 0.1 M NaCl, 1 mM EDTA, and 5% [w/v] TRITON® X-100).4. Add 25 μl of a freshly prepared lysozyme solution (500,000 units/ml in 10 mM Tris-HCl, pH 8.0).5. Mix by vortexing for 3 seconds.6. Incubate the lysis mixture for 30 minutes at 37 °C7. After incubation, place the tube containing the lysis mixture in a boiling water bath for exactly 40 seconds.8. Centrifuge the lysis mixture at 14,000 x g.9. Remove the pellet (cell debris) from the tube using a sterile toothpick.10. Plasmid DNA from the supernatant may then be purified and analyzed.
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
