		Technical Data
P4258-02G	Platelet Derived Growth Factor B (PDGF-B) Chain, Recombinant, Human	10ug

Growth Factors, Cytokines

Storage: -20°CShipping: Blue Ice

Recombinant PDGF-B comprises a 109 amino acid fragment (82-190) corresponding to the mature PDGF-B chain protein and is expressed in E. coli with an amino-terminal hexahistidine tag.

The term ‘PDGF’ refers to a family of disulfide bond- linked dimeric isoforms that act as autocrine and paracrine growth factors and are produced by a variety of cell types other than platelets. They act as potent mitogens for almost all mesenchymally-derived cells. Aberrant expression is involved in certain cancers, fibroproliferative disorders and atherosclerosis.

Applications:
Suitable for use in ELISA, Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
