Information d'application

Restrictions: For Research Use only

Stockage

Format: Lyophilized

Reconstitution: Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1 mg/mL for 500 μg or 1 mg lyophilized powder. Do not mix by vortex or vigorous shaking.

Buffer: Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.

Stock: -20 °C,-80 °C

Stockage commentaire: -20 to -80°C for 12 months as supplied from date of receipt.,-80°C for 3 months after reconstitution.,Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Date de péremption: 12 months

Détail du antigène

Antigène: GM-CSF (CSF2) (Colony Stimulating Factor 2 (Granulocyte-Macrophage) (CSF2))

Autre désignation: GM-CSF

Sujet: Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, natural killer cells, endothelial cells and fibroblasts that functions as a cytokine. The pharmaceutical analogs of naturally occurring GM-CSF are called sargramostim and molgramostim.

Poids moléculaire: 14.6 kDa same as Bis-Tris PAGE result.
