96 Tests PN: B111197

Components:

45x Ab-conjugated beads (S5P4 - human PDGF-BB Ab-bead). PN: B111197A. One vial containing 100 µL of anti-human PDGF-BB conjugated to AimPlex Bead S5P4.

25x Biotin-detection Ab (human PDGF-BB Biotin-dAb). PN: B111197B. One vial containing 100 µL of biotinylated anti-human PDGF-BB.

Lyophilized Standard Mix-Human Group 10, Panel A, 9-Plex. PN: HG1009A. One vial containing lyophilized recombinant BTC, CNTF, FGF-4, Follistatin, IL-19, KGF, PDGF-AA, PDGF-BB, and PIGF-1.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human Human PDGF-BB. Can be multiplexed with other analytes in Human Group 10.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Important: Sample types containing low levels of platelets such as platelet-poor plasma are recommended because PDGF-BB in platelet granules is released upon platelet activation.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Platelet-derived growth factor subunit B 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 (PDGFA) 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 COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Diseases associated with PDGFB include dermatofibrosarcoma protuberans and basal ganglia calcification.
