簡單介紹:
重組人血小板源生長Factor-BB蛋白與其它公司提供的重組蛋白不同,rHuPDGF-BB蛋白產品為采用CFS的無細胞麥胚蛋白合成系統表達出來的重組蛋白,可表達出對細胞有毒性、易被蛋白酶降解的蛋白;并獲得具有良好的可溶性,并有翻譯后修飾、從而部分具有功能的蛋白.同時獨有的全自動蛋白純化技術則簡便高效,將蛋白純化過程中對蛋白的損傷降低到*小程度.重組人血小板源生長Factor-BB蛋白(全長序列)產品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

Purity > 97 % by SDS-PAGE and HPLC analyses.
Biological Activity Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 3 ng/ml, corresponding to a specific activity of > 3.3 × 105 IU/mg.
Physical Appearance 重組人血小板源生長Factor-BB蛋白Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
Endotoxin Less than 1 EU/μg of rHuPDGF-BB as determined by LAL method.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
Storage This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.

Background 重組人血小板源生長Factor-BB蛋白Platelet-derived growth factor (PDGF) presenting in serum but absent from plasma was first discovered in animal study by Lynch and co-workers in the late 1980s. It is a disulfide-linked dimer consisting of two peptides-chain A and chain B. PDGF has three subforms: PDGF-AA, PDGF-BB, PDGF-AB. It is involved in a number of biological processes, including hyperplasia, embryonic neuron development, chemotaxis, and respiratory tubule epithelial cell development. The function of PDGF is mediated by two receptors (PDGFR-α and PDGFR-β).
