Cell Line Authentication Test Recommendations

Authentication of a cell line is the sum of the process by which a line’s identity is verified and shown to be free of contamination from other cell lines and microbes.

Chemically Induced Differentiation of ATCC CL-173 (3T3-L1) Using Single-Component Commercially Available Reagents

3T3-L1 materials from at least two different distribution lots were tested for their ability to differentiate in response to a mixture of insulin, dexamethasone, and IBMX (methylisobutylxanthine). The assay was established according to published protocols and is relatively easy to perform.

Cryogenic Storage of Animal Cells

Cryogenic preservation (storage below -130°C) of cell cultures is widely used to maintain reserves of cell cultures. Besides providing a valuable back-up supply, properly stored cultures also reduce alterations in or loss of culture characteristics.

Guide to Subculturing Cell Line Monolayers

Most cell lines and primary cell cultures grow as a single thickness cell layer (monolayer) or sheet attached to glass or specially treated plastic substrates. In order to keep cultures healthy and actively growing it is usually necessary to subculture them at regular intervals.

Lymphocyte Transformation Using ATCC VR-1492

This technical document describes the procedure recommended for transformation with Epstein-Barr virus (EBV) as described by Caputo et al. in 1995, which is reported to have a success rate of 95%.

Passage Number Effects in Cell Lines

The degree of subculturing a cell line has undergone is often expressed as “passage number,” which can generally be thought of as the number of times cells have been transferred from vessel-to-vessel.
