Stromal cell-derived factor-1 (SDF-1) is a proinflammatory cytokine that belongs to the CXC family of chemokines. The effects of SDF-1 are mediated by its binding to the receptor CXCR4, and sometimes to CXCR7. Both lymphoid (bone marrow, spleen and thymus) and non-lymphoid (stomach, kidney, liver, lung, brain, heart) organs express SDF-1. The most important functions assigned to SDF-1 are angiogenesis, migration of μglia and astrocytes, tissue repair and as chemoattractant to hematopoietic cells. Studies also implicate SDF-1 in survival of human glioma cells via the activation of PI3K/Akt pathway. The other pathways that are activated by SDF-1 include MAPK, NF-κB, paxillin, Crk and other focal adhesion proteins. A variety of human malignancies of pancreas, breast, prostate and glioma exhibit overexpression of CXCR4. High expression of SDF-1 has been observed in lymph nodes, lungs, bone and liver that are the most common sites of metastasis of breast cancer cells This antibody can be used for the localization and detection of human SDF-1/PBSF. It can detect human SDF-1α and SDF-1β.
Specificity
The antibody may be used for neutralization of SDF-1α and SDF-1β, and for localization and detection of human SDF-1/PBSF.
Immunogen
recombinant human SDF-1/PBSF expressed in E. coli.
Application
Anti-SDF-1/PBSF antibody may be used for immunoblotting at a working concentration of 0.1-0.2 μg/ml. For ELISA, the recommended working antibody concentration is 0.5-1.0 μg/ml. The antibody is also suitable for neutralization assays.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline with 5% trehalose..

PBSF/SDF-1 is a CXC chemokine which has unique functions among chemokines. It is essential for viability of the embryo, B lymphopoiesis, bone marrow hematopoiesis and cardiogenesis. A receptor for PBSF/SDF-1 was shown to be CXCR4 that is an entry co-receptor

The alpha-chemokine stromal cell-derived factor (SDF)-1alpha binds to the seven transmembrane G-protein-coupled CXCR-4 receptor and acts to modulate cell migration and proliferation. The signaling pathways that mediate the effects of SDF-1alpha are not well characterized. We studied events following SDF-1alpha
This protocol describes a rapid and efficient feeder-, serum-, and xeno-free method for neutrophil generation from hiPSCs using ETV2 modified mRNA (mmRNA), which directs hematoendothelial programming of hiPSCs. Hematoendothelial progenitors were cultured with GM-CSF, FGF-2, and UM171 to expand myelomonocytic

Local recurrence of glioblastomas is a major cause of patient mortality after definitive treatment. This review discusses the roles of the chemokine stromal cell-derived factor-1 and its receptor CXC chemokine receptor 4 (CXCR4) in affecting the sensitivity of glioblastomas to
The genetic dependencies of human cancers widely vary. Here, we catalog this heterogeneity and use it to identify functional gene interactions and genotype-dependent liabilities in cancer. By using genome-wide CRISPR-based screens, we generate a gene essentiality dataset across 14 human
