PF 4 Human

Short Summary : Platelet Factor-4 Human Recombinant (CXCL4)

Purity : Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Molecular Weight : 7.8 kDa

Accession Number : P02776

Alternative Name/s : CXCL4, PF-4, PF4, Iroplact, Oncostatin-A, SCYB4, MGC138298.

Source : Escherichia Coli.

Amino Acid Sequence/Note: The sequence of the first four N-terminal amino acids was determined and was found to be Glu-Ala-Glu-Glu-Asp.

Appearance/Format : Sterile Filtered white lyophilized powder.

Storage/Note : Lyophilized CXCL4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL4 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.

Formulation/Form : The CXCL4 protein was lyophilized after extensive dialysis against 50mM Tris-HCl pH 8.0 and 150mM NaCl buffer.

Background/Description : CXCL4 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 70 amino acids and having a molecular mass of 7.8 kDa.
