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

Protein Type: Recombinant

Origin: Human

Source: HEK-293 Cells

Purity: >95 % as determined by SDS-PAGE.

Product Details

Protein Characteristics: AA 18-144

Purification tag / Conjugate: This GM-CSF protein is labelled with Biotin.

Brand: MABSol®,UltraLys

Sequence: AA 18-144

Specificity: The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

Characteristics: The product does NOT contain any epitope tags. The protein has a calculated MW of 14.5 kDa. The protein migrates as 18-28 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.

Endotoxin Level: Less than 1.0 EU per μg by the LAL method.

Application Details

Comment:

A chemically labeled biotinylated protein with ultra sensitivity.
The product is produced using a chemical labeling approach. The primary amines in the side chains of lysine residues and the N-terminus of protein are conjugated with biotins.
Chemical labeling usually results in multiple biotin attachment on a single protein molecule, which could potentially lead to higher detection sensitivity.

Target Details

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

Alternative Name: GM-CSF

Background: Granulocyte-macrophage colony-stimulating factor (GM-CSF) is also known as Colony stimulating factor 2 (granulocyte-macrophage), is a cytokine initially characterized by its ability to induce colonies of granulocytes and macrophages from myeloid progenitor cells, and is secreted by macrophages, T cells, mast cells, endothelial cells and fibroblasts. GM-CSF is a cytokine that functions as a white blood cell growth factor. GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes. Monocytes exitthe circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells. Thus, it is part of the immune/inflammatory cascade, by which activation of a small number of macrophages can rapidly lead to an increase in their numbers, a process crucial for fighting infection. The active form of the protein is found extracellularly as a homodimer. Human GM-CSF glycosylated in its mature form. As a part of the immune/inflammatory cascade, GM-CSF promotes Th1 biased immune response, angiogenesis, allergic inflammation, and the development of autoimmunity, and thus worthy of consideration for therapeutic target. GM-CSF has also recently been evaluated in clinical trials for its potential as a vaccine adjuvant in HIV-infected patients. The preliminary results have been promising. GM-CSF is also used as a medication to stimulate the production of white blood cells following chemotherapy.
