Additional Info
| Post Translational Modifications | Processed forms SDF-1-beta(3-72) and SDF-1-alpha(3-67) are produced after secretion by proteolytic cleavage of isoforms Beta and Alpha, respectively. The N-terminal processing is probably achieved by DPP4. Isoform Alpha is first cleaved at the C-terminus to yield a SDF-1-alpha(1-67) intermediate before being processed at the N-terminus. The C-terminal processing of isoform Alpha is reduced by binding to heparin and, probably, cell surface proteoglycans. |
| Function | Chemoattractant active on T-lymphocytes and monocytes but not neutrophils. Activates the C-X-C chemokine receptor CXCR4 to induce a rapid and transient rise in the level of intracellular calcium ions and chemotaxis. SDF-1-beta(3-72) and SDF-1-alpha(3-67) show a reduced chemotactic activity. Binding to cell surface proteoglycans seems to inhibit formation of SDF-1-alpha(3-67) and thus to preserve activity on local sites. Also binds to atypical chemokine receptor ACKR3, which activates the beta-arrestin pathway and acts as a scavenger receptor for SDF-1. Binds to the allosteric site (site 2) of integrins and activates integrins ITGAV:ITGB3, ITGA4:ITGB1 and ITGA5:ITGB1 in a CXCR4-independent manner. Acts as a positive regulator of monocyte migration and a negative regulator of monocyte adhesion via the LYN kinase. Stimulates migration of monocytes and T-lymphocytes through its receptors, CXCR4 and ACKR3, and decreases monocyte adherence to surfaces coated with ICAM-1, a ligand for beta-2 integrins. SDF1A/CXCR4 signaling axis inhibits beta-2 integrin LFA-1 mediated adhesion of monocytes to ICAM-1 through LYN kinase. Inhibits CXCR4-mediated infection by T-cell line-adapted HIV-1. Plays a protective role after myocardial infarction. Induces down-regulation and internalization of ACKR3 expressed in various cells. Has several critical functions during embryonic development.required for B-cell lymphopoiesis, myelopoiesis in bone marrow and heart ventricular septum formation. Stimulates the proliferation of bone marrow-derived B-cell progenitors in the presence of IL7 as well as growth of stromal cell-dependent pre-B-cells. |

Frequently Asked Questions
Common questions about Human SDF-1/CXCL12 (Stromal Cell-Derived Factor 1) Antibody Pair (STJAP00003)
This antibody pair detects human SDF-1/CXCL12 (Stromal Cell-Derived Factor 1), corresponding to UniProt entry P48061. Reactivity is confirmed for human samples only.
The capture antibody is an unconjugated mouse monoclonal antibody, and the detection antibody is a biotin-conjugated goat polyclonal antibody. Both are supplied at 0.5 mg/mL in PBS with 0.04% Proclin 300 and 50% glycerol at pH 7.4.
This antibody pair is validated for use in ELISA. No other assay formats are listed in the product specifications.
Both the capture and detection antibodies were raised against recombinant human SDF-1/CXCL12 protein. The capture antibody was purified using Protein A or G, while the detection antibody was purified by antigen affinity.
Both components should be stored at -20 degrees Celsius for long-term storage. Repeated freeze-thaw cycles should be avoided to maintain reagent integrity.
