Human GM-CSF Protein, premium grade

GMP Version Available: GMP Human GM-CSF Protein   

分子别名(Synonym)

GM-CSF,CSF2,MGC131935

表达区间及表达系统(Source)

Human GM-CSF, premium grade (GMF-H4214) is expressed from human 293 cells (HEK293). It contains AA Ala 18 - Glu 144 (Accession # NP_000749.2 ).

Predicted N-terminus: Ala 18

It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

The protein has a calculated MW of 14.5 kDa. The protein migrates as 25 kDa±3 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 0.01 EU per μg by the LAL method.

宿主蛋白残留(Host Cell Protein)

<0.5 ng/µg of protein tested by ELISA.

宿主核酸残留(Host Cell DNA)

<0.02 ng/μg of protein tested by qPCR.

无菌(Sterility)

The sterility testing was performed by membrane filtration method.

支原体(Mycoplasma)

Negative.

纯度(Purity)

>95% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳(SDS-PAGE)

GM-CSF SDS-PAGE

Human GM-CSF, premium grade on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

SEC-MALS

GM-CSF SEC-MALS

The purity of Human GM-CSF, premium grade (Cat. No. GMF-H4214) is more than 95% and the molecular weight of this protein is around 20-30 kDa verified by SEC-MALS.

Protocol

 

背景(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.
