产品型号：GM-J#023806 -Cryorecovery

产品应用：The CD19-Cre knockin/knockout allele has a Cre recombinase gene inserted into the first coding exon of the CD19 antigen gene (Cd19); both abolishing endogenous Cd19 gene function and placing cre expression under the control of the endogenous Cd19 promoter/enhancer elements. Cre recombinase expression is directed at the earliest stages and throughout B-lymphocyte development and differentiation. Homozygous mice are also useful for studying B cell-deficiency.
