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.
The lyophilized product should be swollen in buffer A for 30 minutes or longer at room temperature. Do not stir with any kind of mechanical stirrer. One gram of powder typically swells to 3-4 mL of the hydrated gel. This, along with other useful information (such as the formulation of buffer A) can be found on the product information sheet (under Documents, above).
Suspensions stored in the refrigerator in the presence of a suitable bacteriostatic agent, such as 20% ETOH, retain IgG binding activity. Another storage option is to put the resin into phosphate buffer saline, pH 7 with about 0.01% preservative (thimerosal or sodium azide).
Protein A Sepharose CL-4B exhibits high chemical and mechanical stability, and is stable over the pH range 2-11. It withstands high concentrations of denaturants, such as urea and guanidine hydrochloride. The gel displays high thermal stability but is not autoclavable. Furthermore, the gel can, if handled with care, be used many times.
It may be possible to clean the resin by washing it with 10-20 volumes of 100 mM Tris or borate buffer, pH8.5, containing 0.5-2.0 M NaCl, followed by 10-20 volumes of 100 mM acetate buffer, pH 4.0, containing0.5-2.0 M NaCl. Re equilibrate the resin with 20 volumes of buffer A.
A table is available on the product information sheet (under Documents, above).
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.
