Platelet Derived Growth Factor AA, Recombinant, Human (PDGF-AA)

Gene Names
PDGFB; SIS; SSV; PDGF2; c-sis; PDGF-2
Purity
Highly Purified
95% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified.
Synonyms
Platelet Derived Growth Factor AA; Recombinant; Human (PDGF-AA); PDGFB active protein
Ordering
For Research Use Only!
Host
E Coli
Purity/Purification
Highly Purified
95% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified.
Form/Format
Supplied as a lyophilized powder. No additives.
Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ser-Ile-Glu-Glu.
Biological Activity
PDGF-AA is fully biologically active when compared to standard. The ED50, calculated by the dose-dependent proliferation of murine BALB/c 3T3 indicator cells (measured by 3H-thymidine uptake) is < 1ng/ml, corresponding to a Specific Activity of 1MIU/mg.
Dimers and Aggregates
1% as determined by silver-stained SDS-PAGE gel analysis.
Endotoxin Level
0.1ng/ug (IEU/ug) of PDGF-AA.
Protein Content
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280nm using the absorbency value of 0.55 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of PDGF-AA as a Reference Standard.
Reconstitution
Reconstitute the lyophilized PDGF-AA in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Preparation and Storage
Lyophilized powder may be stored at 4 degree C for short-term only. Reconstitute to nominal volume by adding sterile dH2O and store at -20 degree C. Reconstituted product is stable for 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
Related Product Information for PDGFB active protein
PDGFs are disulfide-linked dimers consisting of two 12.0-13.5kD polypeptide chains, designated PDGF-A and PDGF-B chains. The three naturally occurring PDGFs. (PDGF-AA, PDGF-BB and PDGF-AB) are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGFs are stored in platelet alpha-granules and are released upon platelet activation. The PDGFs are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGFs have been identified and named PDGFR-alpha and PDGFR-beta. PDGFR-alpha is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-beta interacts with only PDGF-BB and PDGF-AB. PDGF is released when platelets adhere to traumatized tissues. Connective tissue cells near the traumatized region respond by initiating the process of replication.The synthesis of PDGF can be induced by Interleukin-1, Interleukin-6, TNF-alpha, TGF-beta and EGF.

Recombinant Human Platelet Derived Growth Factor-AA is a homodimeric, non-glycosylated, polypeptide chain containing 2 x 125 amino acids and having a total molecular mass of 28511 Dalton.

NCBI Description

The protein encoded by this gene 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 17, at sites where this gene and that for collagen type 1, alpha 1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Feb 2013]

Uniprot Description

Function: Growth factor that plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. Potent mitogen for cells of mesenchymal origin. Required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, lung, heart and placenta. Required for normal blood vessel development, and for normal development of kidney glomeruli. Plays an important role in wound healing. Signaling is modulated by the formation of heterodimers with PDGFA

By similarity.

Subunit structure: Homodimer; antiparallel disulfide-linked dimer. Heterodimer with PDGFA; antiparallel disulfide-linked dimer. The PDGFB homodimer interacts with PDGFRA and PDGFRB homodimers, and with heterodimers formed by PDGFRA and PDGFRB. The heterodimer composed of PDGFA and PDGFB interacts with PDGFRB homodimers, and with heterodimers formed by PDGFRA and PDGFRB. Interacts with XLKD1

By similarity. Ref.19 Ref.24

Subcellular location: Secreted. Note: Released by platelets upon wounding.

Tissue specificity: Expressed at high levels in the heart, brain (sustantia nigra), placenta and fetal kidney. Expressed at moderate levels in the brain (hippocampus), skeletal muscle, kidney and lung. Ref.20

Involvement in disease: A chromosomal aberration involving PDGFB is found in dermatofibrosarcoma protuberans. Translocation t(17;22)(q22;q13) with PDGFB. Ref.21

Pharmaceutical use: Available under the name Regranex (Ortho-McNeil). Used to promote healing in diabetic neuropathic foot ulcers.

Sequence similarities: Belongs to the PDGF/VEGF growth factor family.

Product Notes

The PDGFB pdgfb (Catalog #AAA650257) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ser-Il e-Glu-Glu. It is sometimes possible for the material contained within the vial of "Platelet Derived Growth Factor AA, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
