Applications
Our Abpromise guarantee covers the use of ab9797 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| Neutralising | Use at an assay dependent dilution. To yield one-half maximal inhibition [ND50] of the biological activity of hSDF1 alpha (100 ng/ml), a concentration of 2-4 µg/ml of this antibody is required. | |
| ICC/IF | Use at an assay dependent concentration. PubMed: 21858102 | |
| Indirect ELISA | Use a concentration of 0.5 - 2 µg/ml. (using 100 µl/well antibody solution). This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human SDF1 alpha. | |
| Sandwich ELISA | Use a concentration of 0.5 - 2 µg/ml. (using 100 µl/well antibody solution). This antigen affinity purified antibody, in conjunction with ab84277 as a detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human SDF1 alpha. | |
| WB | Use at an assay dependent concentration. To detect hSDF-1a by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant hSDF-1a is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions. | |
| ELISA | Use at an assay dependent concentration. To detect hSDF-1a by direct ELISA (using 100µl/well antibody solution) a concentration of at least 0.5µg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2 - 0.4 ng/well of recombinant hSDF-1a. | |
| IHC-Fr | Use at an assay dependent concentration. | |
| IHC-P | Use at an assay dependent dilution. |
Target
-
FunctionChemoattractant active on T-lymphocytes, 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. Also binds to atypical chemokine receptor ACKR3, which activates the beta-arrestin pathway and acts as a scavenger receptor for SDF-1. 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. 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.
-
Tissue specificityIsoform Alpha and isoform Beta are ubiquitously expressed, with highest levels detected in liver, pancreas and spleen. Isoform Gamma is mainly expressed in heart, with weak expression detected in several other tissues. Isoform Delta, isoform Epsilon and isoform Theta have highest expression levels in pancreas, with lower levels detected in heart, kidney, liver and spleen.
-
Sequence similaritiesBelongs to the intercrine alpha (chemokine CxC) family.
-
Developmental stageIsoform Alpha is ubiquitously expressed in fetal tissues. Isoform Beta and isoform Delta have more limited expression patterns, with highest levels detected in fetal spleen and fetal liver, respectively. Isoform Gamma and isoform Theta are weakly detected in fetal kidney.
-
Post-translational
modificationsProcessed 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. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-SDF1 antibody (ab9797)ab9797 staining SDF1 alpha in human colorectal adenocarcinoma tissue by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections). Tissue underwent heat mediated antigen retrieval in sodium citrate buffer (pH 6.0). The primary antibody was used at 0.5 ug/ml and incubated with sample at 4°C overnight. A HRP-labeled polymer detection system was used with a DAB chromogen.

Cells were either unstimulated (right) or stimulated with direct current (left) before being fixed in formalin and permeabilized in 0.1% Triton X-100 in PBS. Samples were incubated with primary antibody (1/200 in PBS) and an AlexaFluor®488-conjugated anti-rabbit polyclonal IgG (1/200) was used as the secondary antibody. -
