Animal-Free GM-CSF Protein, Pig (His)

The GM-CSF protein acts as a potent cytokine that coordinates the growth and differentiation of hematopoietic precursor cells of different lineages, including granulocytes, macrophages, eosinophils, and erythrocytes. Structurally, GM-CSF exists as a monomer and its signaling is mediated through a dodecamer complex. Animal-Free GM-CSF Protein, Pig (His) is the recombinant pig-derived animal-FreeGM-CSF protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free GM-CSF Protein, Pig (His) is 127 a.a., with molecular weight of ~15.3 kDa.

GM-CSF Protein serves as a potent cytokine, orchestrating the growth and differentiation of hematopoietic precursor cells across diverse lineages, including granulocytes, macrophages, eosinophils, and erythrocytes. Structurally, GM-CSF exists as a monomer, and its signaling is mediated through a dodecameric complex. This complex comprises two head-to-head hexamers, each featuring two alpha, two beta, and two ligand subunits, underscoring the intricacy of the receptor assembly and the specificity of GM-CSF in modulating cellular responses.

Measure by its ability to induce proliferationin TF-1 cells. The ED₅₀ for this effect is <3 ng/mL.

Lyophilized from a solution containing 1X PBS, pH 7.4.

<0.1 EU per 1 μg of the protein by the LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
