SDF-1 ALPHA human

Cat. No.: S755852

GRADE & PURITY Animal Free, Recombinant, ≥98%(SDS-PAGE&HPLC), expressed in E. coli

개요

SDF-1α (stromal cell-derived factor 1 α) and β are stromal derived CXC chemokines, and signal through the CXCR4 (C-X-C motif chemokine receptor). SDF1α is an isoform of CXCL12 (C-X-C motif chemokine 12, also referred to as SDF-1). The gene is mapped to human chromosome 10q11. Recombinant human SDF-1a is an 8.0kDa protein containing 68 amino acid residues.

Application:

SDF-1α (stromal cell-derived factor 1 α) human has been used to study the role of SDF-1α in cell migration and survival after TGF (transforming growth factor)-β-induced EMT (epithelial–mesenchymal transition) in hepatoma cells. It has been used to study podia formation, migration, proliferation and cell-cell adhesion of human hematopoietic progenitor cells in presence of SDF-1α.

SDF-1α (stromal cell-derived factor 1 α) human has been used in the chemotaxis assay of neural crest cells (NCCs) and as a component of Dulbecco′s modified Eagle′s medium (DMEM) in migration assay of human mesenchymal stem cells (hMSCs).

자주 묻는 질문

How should this product be stored?

Store at ?20 °C. Freezer storage is required to maintain the specified shelf life.

What does Animal Free mean?

Animal Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

What does Recombinant mean?

Recombinant is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Recombinant is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
