Preparation and Storage
Stability and Storage
Shipped at 4°C. After reconstitution store at -20ºC. Avoid freeze / thaw cycles.
Constituents: 1% Human serum albumin, 10% Trehalose
This product is an active protein and may elicit a biological response in vivo, handle with caution.
ReconstitutionIt is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. Following reconstitution short-term storage at 4°C is recommended, and longer-term storage of aliquots at -18 to -20°C. Repeated freeze thawing is not recommended.
- Colony stimulating factor
- Colony Stimulating Factor 2
- Colony stimulating factor 2 (granulocyte-macrophage)
FunctionCytokine that stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes.
Sequence similaritiesBelongs to the GM-CSF family.
- Information by UniProt
1D SDS-PAGE of ab88382 before and after treatment with glycosidases to remove oligosaccharides.
Lane 1: ab88382
Lane 2: ab88382 treated with PNGase F to remove potential N-linked glycans
Lane 3: ab88382 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. Drop in MWt after treatment with PNGase F indicates the presence of N-linked glycans. Subsequent small drop in MWt after treatment with glycosidase cocktail suggests possible presence of O-linked glycans. Additional bands in lane 2 and lane 3 are glycosidase enzymes.
A sample of ab88382 without carrier protein was reduced and alkylated. 40 μg protein was loaded, focused on a 3-10 IPG strip then run on a 4-20% Tris-HCl 2D gel. Spot trains (Deep Purple™ stained) indicates the presence of multiple isoforms of GM-CSF.
Densitometry of protein isoforms visualised by 2-DE.
The densitometry scan demonstrates the purified human cell expressed protein exists in multiple isoforms, which differ according to their level of post-translational modification.
The triangle indicates the theoretical MWt and pI of the protein.
