Biolegend, 619953, Ultra-LEAF™ Purified anti-human G-CSF Antibody, 100μg

Human G-CSF was cloned from a human squamous carcinoma cell line and is the key hematopoietic cytokine involved in the control of neutrophil production. Therefore, it is a critical regulator of innate immunity against bacterial infections. G-CSF mobilizes stem cells indirectly by down-regulating the expression of CXCL12 on marrow osteoblasts and by releasing neutrophil and monocyte proteolytic enzymes, including neutrophil elastase, cathepsin G, and matrix metalloproteinase-9, which in turn degrade important HSC trafficking and adhesion molecules c-kit, VCAM-1, and CXCR4. In addition, G-CSF possesses immunosuppressive effects on monocytes/macrophages, dendritic cells, and T lymphocytes. The receptor for G-CSF is expressed not only in hematopoietic cells, it is also expressed in cardiomyocytes, skeletal muscle, and neurons. G-CSF influences mouse skeletal muscle development and regeneration by stimulating myoblast proliferation. In vitro , G-CSF displays strong antiapoptotic activity in neuronal cells.

Q: Do you guarantee that your antibodies are totally pathogen free?
A: BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
Q: Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
A: No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
Q: Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
A: No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.
Q: Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
A: We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
