ActoFactor™ Recombinant Human Platelet factor 4

Specification

Cat.No.

CSC-CTK0470

Description

PF-4 is a CXC chemokine that is expressed in megakaryocytes and stored in the alpha-granules of platelets. PF-4 is chemotactic towards neutrophils and monocytes and has been shown to inhibit angiogenesis. Recombinant human PF-4 is a 7.8 kDa protein containing 70 amino acid residues, including the four highly conserved residues present in CXC chemokines.

E.coli

Purity

Greater than 98% as determined by SDS-PAGE and HPLC analysis.

Activity

Determined by its ability to chemoattract human fibroblasts using a concentration range of 1.0- 10.0 ng/ml.

Endotoxin Level

Less than 1 EU/μg.

Formulation

Sterile-filtered through a 0.2 micron filter and lyophilized with no additives.

Reconstitution

Please centrifuge product briefly before opening the vial. Reconstitute in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can 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 dessicated at -20°C. Reconstituted protein 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.
