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

The GM-CSF protein functions as a key cytokine that promotes the growth and differentiation of hematopoietic precursor cells of different lineages, such as granulocytes, macrophages, eosinophils, and erythrocytes. In its monomeric form, GM-CSF acts as a signaling molecule, orchestrating complex receptor assemblies. Animal-Free GM-CSF Protein, Human (His) is the recombinant human-derived animal-FreeGM-CSF protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free GM-CSF Protein, Human (His) is 127 a.a., with molecular weight of ~15.4 kDa.

GMP GM-CSF Protein functions as a pivotal cytokine, fostering the growth and differentiation of hematopoietic precursor cells spanning diverse lineages, such as granulocytes, macrophages, eosinophils, and erythrocytes. In its monomeric form, GMP GM-CSF serves as a signaling molecule, orchestrating a complex receptor assembly. This receptor complex takes the shape of a dodecamer, consisting of two head-to-head hexamers, each composed of two alpha, two beta, and two ligand subunits. This structural intricacy underscores the specificity and regulatory role of GMP GM-CSF in directing cellular responses within the hematopoietic system.

Measure by its ability to induce TF-1 cells proliferation. The ED₅₀ for this effect is <80 pg/mL. The specific activity of recombinant human GM-CSF is approximately >1 x 10⁷ IU/mg.

Lyophilized powder

Lyophilized from a solution containing 1X PBS, pH 8.0.

<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. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

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.

Room temperature in continental US; may vary elsewhere.
