Product Specifications
Size:
50 µg
Protein Information
Protein Name & Synonyms:
SDF-1 alpha / CXCL12a
Target Species:
- Human
Antibody Specifications
Concentration (lot specific):
IgG concentration 0.1 mg/ml after reconstitution
Preparation:
Antisera to human SDF-1 alpha were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG prepared by affinity chromatography.
Reconstitution:
Reconstitute with 0.5ml sterile PBS containing 0.1% Bovine Serum Albumin.. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. RayBiotech recommend that the vial is gently mixed after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended.
This product may be used under either reducing or non-reducing western blotting conditions.
Specificity
This product recognizes human SDF-1 alpha, otherwise known as CXCL12a, a 68 amino acid stromal cell derived CXC chemokine, which arises from alternative splicing of the SDF-1 gene. The two isoforms, SDF-1 alpha and SDF-1 beta, share an identical amino acid sequence, except for an additional four residues in the C-terminal region of the beta isoform.
SDF-1 binds with high-affinity to the G proteinââcoupled receptor CXCR4 (fusin) and acts as a chemoattractant for T and B lymphocytes, monocytes and migratory neurons, and is a vital factor in hematopoiesis and angiogenesis. By competitively binding to CXCR4, SDF-1 acts as an inhibitor for the CXCR4-mediated entry of HIV-1 virus into target T-cells, and the SDF-1-CXCR4 interaction is important for the regulation of trafficking of normal and malignant stem cells.

Storage/Stability
Prior to reconstitution store at +4 °C.
After reconstitution store at -20 °C.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
If stored in this manner, this product is stable for 12 months after receipt.
