Rat SDF 1b Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant SDF 1b based upon sequence from Rat
Host: QP10863 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of SDF 1b was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized SDF-1b in sterile 18MΩ.cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: The specific activity as determined by its ability to chemoattract human peripheral blood monocytes at 100-150ng/ml corresponding to a Specific Activity of 6,667-10,000IU/mg.
Amino Acid Sequence: KPVSLSYRCP CRFFESHVAR ANVKHLKILN TPNCALQIVA RLKSNNRQVC IDPKLKWIQE YLDKALNKRL KM
Purity: Greater than 97.0% as determined by:(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Buffer: The Rat SDF1B protein was lyophilized from a concentrated (1 mg/ml) sterile solution containing 20mM Phsophate buffer pH 7.4 and 0.15M NaCl.
Storage Conditions: Lyophilized SDF-1b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL12 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
