U2OS RFP-ACTB

Tested for Mycoplasma, sterility, post-freeze viability, short terminal repeat (STR) analysis for cell line identification, PCR assay for cell line species confirmation.

This product is a human U2OS cell line in which the genomic ACTB gene has been endogenously tagged with a Red Fluorescent Protein (RFP) gene using CompoZr^® Zinc Finger Nuclease technology. Integration resulted in endogenous expression of the fusion protein in which RFP is attached to the N-terminus of actin. Fluorescence imaging shows that the actin can polymerize to form the characteristic pattern of actin filaments. Addition of Cytochalasin B to the cell line causes the expected shortening of actin filaments. This stable cell line was expanded from a single clone. The target′s gene regulation and corresponding protein function are preserved in contrast to cell lines with overexpression via an exogenous promoter.
