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'.
Aldrich Products
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'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.

How do I handle Cell Line frozen cells upon arrival?
Upon receipt, frozen ampules should be transferred directly to vapor phase liquid nitrogen without delay (-135°C) or liquid phase liquid nitrogen if vapor phase is not available. DO NOT use a -80°C freezer as an alternative; this will result in loss of viability.
Why is Vapor Phase Liquid Nitrogen preferred for storage of Cell Line cells?
If ampules are immersed into liquid phase of liquid nitrogen, it increases the risk of the liquid seeping into the vial. This could lead to problems of cross-contamination and increased risk of the ampule exploding when thawed.
How do I resuscitate/thaw frozen Cell Line cells?
A protocol for thawing cells can be found in the ECACC handbook.
What medium should I use when I thaw the Cell Line cells?
The medium for each cell line is listed on the product page. It is specific to each cell line. If not visible on the Sigma-Aldrich website product page, the HPA website also contains the same information (www.hpacultures.org.uk). The product number for the cell line is the same on either site.
What passage are my Cell Line cells?
If the passage of the cells is known, it is listed on the product page at the HPA website (www.hpacultures.org.uk).
How many Cell Line cells are in the vial?
Each vial of cells contains 2-3 x 106 cells in 1 ml of freezing media. This is in a 1.8 mL ampule. For exceptionally large cells, counts may decrease. Suspension cells, generally smaller cells, may contain as many as 4-5 x 106 cells/vial to assure optimal viability upon thaw.
Are my Cell Line cells mycoplasma tested?
ECACC routinely tests all manufactured cell banks for mycoplasma.
How to freeze down Cell Line cells to make a cell stock?
A protocol for freezing down cells for cell stocks can be found in the ECACC manual.
Are the Cell Line cells tested for viral pathogens?
HPA Cultures does not perform any viral testing on the cell lines.
