Human LIF (leukemia inhibitory factor) suppresses the differentiation of murine embryonic stem cells (ESCs) and is widely used in ESC and induced pluripotent stem cell (iPSC) culture. Qkine human LIF protein is a 17 kDa highly pure, bioactive, animal origin-free and carrier-protein free for reproducible results in stem cell culture.

Quantitative luciferase reporter assay shows that both LIF (Qk036, green) and alternative supplier LIF (Supplier B, black) have high bioactivity with an EC50 of 0.28 ng/ml (16 pM) and 0.29 ng/ml (17 pM), respectively. Data for Qk03 lot #104293.

Human LIF protein (Qk036) migrates as a single band at 20 kDa in non-reducing (NR) and upon reduction (R). Purified recombinant human LIF protein (3 μg) was resolved using 15% w/v SDS-PAGE in reduced (+ beta -mercaptoethanol, R) and non-reduced conditions (NR) and stained with Coomassie Brilliant Blue R250.

uciferase reporter assay shows equivalent bioactivity of Qkine LIF (Qk036, green) and alterna. nhibitory Factor (LIF) belongs to the IL-6 cytokine family and regulates embryonic development, immune response, and inflammation. LIF is essential to maintain stem cell pluripotency, so it is widely used in embryoni.

2025年3月7日 · Human LIF (leukemia inhibitory factor) protein suppresses the differentiation of embryonic stem cells (ESCs) and is widely used in ESC and iPSC culture. Human LIF can be used in the maintenance of both murine and human ESCs in feeder or feeder-free chemically defined culture systems.
