Rat Leukemia Inhibitory Factor, Active Protein, Cat#RPU60309
SDS-PAGE
Leukemia inhibitory factor (LIF), is an interleukin 6 class cytokine that affects cell growth by inhibiting differentiation. LIF as a cytokine also has another fuction including: the growth promotion and cell differentiation of different types of target cells, influence on bone metabolism, cachexia, neural development, embryogenesis and inflammation. To evaluate the activty of recombinant rat LIF, the K562 cells were were seeded into triplicate wells of 96-well plates at a density of 5,000 cells/well with5% serum standard 1640  which contains various concentrations of recombinant rat LIF. After incubated for 72h, cells were observed by inverted microscope and cell proliferation was measured by Cell Counting Kit-8 (CCK-8). Briefly, 10 ul of CCK-8 solution was added to each well of the plate, then the absorbance at 450 nm was measured using a microplate reader after incubating the plate for 2-4 hours at 37 °C. After incubation with LIF for72h, proliferative inhibition of K562 cells observed by inverted microscope. Cell viability was assessed by CCK-8(Cell Counting Kit-8 ) assay after incubation with recombinant LIF for72h. It was obvious that LIF significantly inhibit cell viability of K562 cells. The ED50 is 1.44μg/ml.

Let customers speak for us

from 218 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
