Description EGF (Epidermal Growth Factor) is a small molecular polypeptide composed of 53 amino acid residues and is a member of the EGF family. It binds to specific receptors on...

Description The recombinant human Fms-Related Tyrosine Kinase 3 Ligand (FLT3L/Flt3 Ligand) is a high-purity, four-helical bundle cytokine produced in HEK-293 expression systems, typically existing as a noncovalently-linked dimer. As a...

Description As a master regulator of Th2 immunity, IL-4 activates the JAK1/3-STAT6 signaling cascade via the IL-4Rα/γc receptor complex, directing naive CD4+ T-cell differentiation into Th2 effectors secreting IL-5/IL-13 while...

Description The recombinant human IL-12 fusion protein is a heterodimer produced by transient transfection in HEK-293 cells, consisting of an IL-12A (p35) subunit with a 6×his-tag and an IL-12B (p40)...

Description M-CSF is a disulfide-linked homodimeric glycoprotein and core member of the colony-stimulating factor family. By specifically binding the c-Fms receptor (CSF-1R/CD115), it induces receptor dimerization and internalization and activates...

Description The recombinant human Tumor Necrosis Factor Alpha (TNF-α) protein is a high-purity homotrimeric cytokine produced in HEK-293 expression system via transient transfection, featuring a C-terminal polyhistidine tag for nickel-affinity...

Description The recombinant human leukemia inhibitory factor (LIF) protein is transiently expressed in HEK-293 cells and features a C-terminal His-tag for purification. As a pleiotropic IL-6 family cytokine, LIF signals...

Description The three mammalian isoforms, TGF-β1, β2, and β3, signal through the same receptor and elicit similar biological responses. They are multifunctional cytokines that regulate cell proliferation, growth, differentiation, and...
