GripTite™ 293 MSR Cell Line

The GripTite™ 293 MSR Cell Line is a genetically engineered Human Embryonic Kidney (HEK 293) cell line that expresses the human macrophage scavenger receptor and strongly adheres to standard tissue culture plates for dependable results. Developed from a 293-H subclone, GripTite™ 293 MSR cells show the same fast cell growth, high transfection efficiency, and high-level expression characteristics of the parental 293-H cells. Unlike most 293 cells, GripTite™ 293 MSR cells dont wash away during the repeated manipulations of routine tissue culture or plate washing protocols (Figure 1). Their superior adherence enables reliable reproduction of ligand-binding, enzymatic, or immunofluorescence assay results.

Use in High-Throughput Applications
The GripTite™ 293 MSR cells enhance performance in high-throughput cell-based, as well as standard tissue culture, applications. Uncontrolled cell loss during high-throughput protocols leads to unreliable results and expensive, time-consuming repeat experiments. Since GripTite™ 293 MSR cells adhere to standard tissue culture treated plastic, theres no need for the costly poly-lysine coated plates typically used in high-throughput analysis. The GripTite™ 293 MSR cells withstand automated plate washing and protocols using liquid handling robots on standard tissue culture plates without significant cell loss (Figure 2).
