产品描述

概述

CXCL12 also known as SDF-1 is belonging to the CXC chemokine family. Murine CXCL12 is expressed as two isoforms that differ only in the C-terminal tail. Both SDF-1 isoforms undergo proteolytic processing of the first two N-terminal amino acids. Contrast to SDF-1β, SDF-1α is shorter by four amino acids at the C-terminal tail. On the cell surface, the receptor for this chemokine is CXCR4 and syndecan4. CXCL12 is strongly chemotactic for T-lymphocytes, monocytes, but not neutrophils. SDF-1 is highly conserved between species, murine CXCL12α shares approximately 93 % amino acid sequence identity with human CXCL12α.

属性

Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Purity > 97 % by SDS-PAGE and HPLC analyses.
Source Escherichia coli.
Biological Activity Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human peripheral blood monocytes is in a concentration range of 50-100 ng/ml.
Formulation Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
Endotoxin Less than 1 EU/μg of rMuSDF-1α/CXCL12α as determined by LAL method.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 C. Further dilutions should be made in appropriate buffered solutions.
