Function

Shows 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.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Isoform 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

Product Specifications

Recombinant Human Stromal cell-derived factor 1 protein (CXCL12) is a recombinant protein from Homo sapiens (Human), expressed in E.Coli, covering amino acids 22-93aa, with Tag-Free tag, molecular weight 8.5 kDa, purity >97% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.

Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.

Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.

Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.
