ActoFactor™ Recombinant Mouse Chemokine (C-X-C motif) ligand 12 (beta)
- Specification
- Recommended Products
Cat.No.
CSC-CTK0779
Description
Recombinant murine SDF-1 beta produced in E. coli is a non-glycosylated, polypeptide chain of 72 amino acids and a molecular mass of 8,513 Dalton.
Species
Mouse
Product Overview
Mouse Cxcl12 expressed in E.coli
Molecular Mass
8.5 kDa
Size
CAT# CSC-CTK0779-10 (10 μg); CAT# CSC-CTK0779-50 (50 μg)
Expression System
E.coli
Purity
Greater than 98% as determined by SDS-PAGE, FPLC and RP-HPLC analysis.
Activity
Murine SDF-1 beta is fully biologically active when compared to a standard. The specific activity is determined by its ability to chemoattract human monocytes at concentrations ranging between 50-100 ng/ml.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Sterile-filtered, white, lyophilized (freeze-dried) powder. Lyophilized from a concentrated (1 mg/ml) solution containing no additives.
Reconstitution
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rMu SDF-1 beta should be used immediately or stored long- term in undiluted working aliquots at -20°C. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
