产品描述

Platelet-Derived Growth Factor BB Human Recombinant is a homodimeric, non-glycosylated, polypeptide chain containing 2x109 amino acids (218 amino acids in total) and having a molecular mass of 24.3 kDa. PDGF-BB is purified by proprietary chromatographic techniques.

Product Data

Purity Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. Source Escherichia Coli.
Phycical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Shipping Condition Shipped at Room temp.
Synonyms Glioma-derived growth factor; GDGF; Osteosarcoma-derived Growth Factor; ODGF; SIS; SSV; PDGF2; c-sis; FLJ12858; PDGF-BB; PDGF B-chain; Platelet-derived growth factor beta polypeptide.
Amino Acid Sequence SLGSLTIAEP AMIAECKTRT EVFEISRRLI DRTNANFLVW PPCVEVQRCS GCCNNRNVQC RPTQVQLRPV QVRKIEIVRK KPIFKKATVT LEDHLACKCE TVAAARPVT.
Solubility It is recommended to reconstitute the lyophilized Platelet-derived Growth Factor-BB in sterile18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability Lyophilized Platelet-derived Growth Factor BB although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution PDGF BB should be stored at 4°C between 2-7 days and for future use below -18°C .Please prevent freeze-thaw cycles.
Biological Activity Determined by the dose-dependent stimulation of the proliferation of Balb/c 3T3 cells. The expected ED50 for this effect is 1.0-3.0 ng/ml.
Formulation Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH7.4.

Introduction

PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 7, at sites where this gene and that for COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two splice variants have been identified for this gene.

Biological Activity

Determined by the dose-dependent stimulation of the proliferation of Balb/c 3T3 cells. The expected ED50 for this effect is 1.0-3.0 ng/ml.

Stability

Lyophilized Platelet-derived Growth Factor BB although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution PDGF BB should be stored at 4°C between 2-7 days and for future use below -18°C .Please prevent freeze-thaw cycles.
