Application

This product is a human THP-1 monocyte cell line in which a landing pad cassette has been integrated into the AAVS1 safe harbor locus using CompoZr^® Zinc Finger Nuclease technology. The mKATE2 fluorescence gene was integrated following the EF1a promoter and flanked by unique Cre-lox sites. The design of this landing pad cassette allows for easy, fast, and affordable genetic modification using Cre recombinase. mKATE2 can easily be exchanged for a payload of the user’;s choice using Cre recombinase and a targeting vector with appropriate lox sites. Cells can then be sorted via fluorescence-activated cell sorting (FACS) for loss of mKATE2 expression as a surrogate for successful integration of the targeting vector. Approximately 7-10 days are required for loss of the mKATE2 signal in successfully targeted cells. See technical bulletin for detailed protocols.

Cell Line Description

These cells were derived from the peripheral blood of a 1-year old male with acute monocytic leukemia. These cells have Fc and C3b receptors and lack surface and cytoplasmic immunoglobulins. They stain positive for α-napthhyl butyrate esterase, produce lysozymes, and are phagocytic (both latex beads and sensitized erythrocytes). They can restore the response of purified T lymphocytes to Concanavalin A, show increased CO2 production on phagocytosis, and can be differentiated into macrophage-like cells using, for example, DMSO.

Features and Benefits

These cells contain the mKATE2 fluorescence gene flanked by unique Cre-lox sites inserted in the AAVS1 safe harbor gene. These THP-1 cells are grown in suspension with a doubling time of approximately 24 hours.

General description

The STR profile of this cell line matches that of its parental cell line ATCC^®Catalog No. TIB-202. THP-1 are a human monocyte cell line isolated from the peripheral blood of a male infant with acute monocytic leukemia. The cells are phagocytic and lack surface and cytoplasmic immunoglobulins. Differentiation can be induced with TPA.
