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.
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.
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.
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.
Quality
Tested for Mycoplasma, bacterial and fungal content, post-freeze viability, short terminal repeat (STR) analysis for cell line identification.

The Cre-lox system is an important tool for genetic manipulation. To promote integrative reactions, two strategies using mutant lox sites have been developed. One is the left element/right element (LE/RE)-mutant strategy and the other is the cassette exchange strategy using

We describe an optimized system for the easy, effective, and precise modification of the Escherichia coli genome. Genome changes are introduced first through the integration of a 1.3 kbp Landing Pad consisting of a gene conferring resistance to tetracycline (tetA)

To circumvent the silencing effect of transgene expression in human embryonic stem cells (hESCs), we employed the Cre recombination-mediated cassette exchange strategy to target the silencing-resistant site in the genome. We have identified new loci that sustain transgene expression during
