Description

LIF (Leukemia Inhibitory Factor) prompts terminal differentiation in leukemic cells, inducing hematopoietic and neuronal cell differentiation.It also stimulates acute-phase protein synthesis in hepatocytes.LIF's multifaceted role underscores its significance in regulating hematopoiesis, neurogenesis, and hepatic responses.LIF Protein, Mouse (HEK293, His) is the recombinant mouse-derived LIF protein, expressed by HEK293 , with C-His labeled tag.

Background

LIF (Leukemia Inhibitory Factor) exhibits the capability to prompt terminal differentiation in leukemic cells, showcasing a diverse range of activities. Notably, it induces hematopoietic differentiation in both normal and myeloid leukemia cells, facilitates neuronal cell differentiation, and stimulates the synthesis of acute-phase proteins in hepatocytes. This multifaceted role underscores LIF's significance in orchestrating various cellular processes, contributing to the regulation of hematopoiesis, neurogenesis, and hepatic responses.

Verified Bioactivity

Measured by its ability to inhibit the proliferation of M1 mouse myeloid leukemia cells. The ED50 for this effect is typically 0.1-0.5 ng/ml.
