产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Cynomolgus M-CSF/CSF-1 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Glu33-Leu255.[Accession | XP_045221641.1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 26.26 kDa. Due to glycosylation, the protein migrates to 45-55 kDa based on Tris-Bis PAGE result.

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

纯度(Purity)

> 95% as determined by Tris-Bis PAGE

制剂(Formulation)

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

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

SPR Data

Cynomolgus M-CSF R, His Tag immobilized on CM5 Chip can bind Cynomolgus M-CSF, His Tag with an affinity constant of 0.889 μM as determined in SPR assay (Biacore T200).

背景(Background)

CSF-1, also known as M-CSF , is a four alpha -helical-bundle cytokine that is the primary regulator of macrophage survival, proliferation and differentiation. CSF-1 is also essential for the survival and proliferation of osteoclast progenitors.CSF-1 is cytokine that plays an essential role in the regulation of survival, proliferation and differentiation of hematopoietic precursor cells, especially mononuclear phagocytes, such as macrophages and monocytes. Promotes the release of proinflammatory chemokines, and thereby plays an important role in innate immunity and in inflammatory processes. This mutation leads to a deletion of exons 2-7 of the EGFR gene and renders the mutant receptor incapable of binding any known ligand.

分子别名(Synonyms)

CSF1; CSF-1; MCSF; M-CSF; MGC31930; Lanimostim
