$20.00

From Ruth Sager, Sidney Farber Cancer Institute, December 1983

This is Sager’s basic wild type strain. It has the wild type alleles at the NIT1 and NIT2 loci, and should be green in the dark. Sager’s original publication called it 21gr, but 21 gr has become the more prevalent usage over the years.

This strain was the source for most of the cDNA libraries, and subsequent EST sequences, in the Chlamydomonas Genome Project, and is our recommended choice for a wild type strain that grows on nitrate.
