重组人碱性成纤维细胞生长因子(耐热型)
碱性成纤维细胞生长因子(bFGF)是成纤维细胞生长因子(FGF)家族中的一类具有促有丝分裂活性的多肽。bFGF能够高效诱导多种来源于中胚层和神经外胚层的细胞进行DNA合成。然而,在细胞生物学研究中,天然bFGF的应用受到限制,主要原因是在生理温度下其稳定性较差、易于降解。ScienCell推出的重组人碱性成纤维细胞生长因子(耐热型)经过工程化改造,具有更高的稳定性,其生物活性维持时间显著长于天然bFGF。使用该产品(rhbFGFTS)时,无需添加高浓度的FGF2,也无需每日更换含新鲜FGF2的培养基。该重组蛋白与155个氨基酸长度的人源bFGF具有超过97%的氨基酸序列同源性,并且未改变其与FGF受体的结合位点。
Basic Fibroblast Growth Factor (bFGF) is a member of the FGF family of mitogenic peptides. bFGF is extremely efficient at inducing DNA synthesis in a variety of cell types from mesoderm and neuroectoderm lineages. Use of native bFGF in cell biology however, is limited by the fact that bFGF rapidly degrades at physiological temperatures. ScienCell’s Recombinant Human Basic Fibroblast Growth Factor Thermostable is engineered for greater stability, which is bioactive longer than native bFGF. By using rhbFGFTS, supplementation with artificially high concentrations of FGF2 or daily media changes with fresh FGF2 are not necessary. The rhbFGFTS shares more than 97% amino acid identity with the 155-amino-acid human bFGF and leaves the FGF receptor binding sites unmodified.
