Independent Claim
78 words
A method for identifying a novel gene or gene fragment comprising the steps of: synthesizing a DNA probe comprising a DNA sequence homologous to at least one DNA sequence within a murine embryonic cDNA library selected from the group consisting of UESL ATCC #69022, BSL ATCC #69026, 2CSL ATCC #69027, and 8CSL ATCC #69024, labeling the DNA probe, and hybridizing the labeled DNA probe to the selected library, said label permitting identification of the gene or gene fragment.
