Source / Purification

Recombinant human FGF basic (hFGF basic) Pro143-Ser288 (Accession #NP_001997) was produced in E. coli at Cell Signaling Technology.

Cell Signaling Technology公司生产的重组人源碱性成纤维细胞因子(hFGF basic)脯氨酸143-丝氨酸288(编号NP_001997)在大肠杆菌中表达。

Molecular Characterization

Based on amino acid sequencing, 60-80% of recombinant hFGF basic starts at the amino-terminal Pro143 (PALPE) and has a calculated MW of 16,539. The remainder is missing Pro143 and starts at Ala144 (ALPED). DTT-reduced and non-reduced protein migrate as 17 kDa polypeptides.



>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hFGF basic. All lots are greater than 98% pure.

6 μg还原和非还原的重组人源FGF 由SDS-PAGE测定大于98%。所有批次产品纯度均大于98%。


The bioactivity of recombinant hFGF basic was determined in a NIH/3T3 cell proliferation assay. The ED50 of each lot is between 0.2 - 1.0 ng/ml.

重组人源碱性FGF的生物活性由NIH/3T3细胞增殖实验测定。其每个批次的ED50在 0.2-1.0 ng/ml之间。

Coomassie Gel

Coomassie Gel

The purity of recombinant hFGF basic was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant hFGF basic and staining overnight with Coomassie Blue.重组hFGF basic 的纯度用SDS-PAGE验证,6 µg 还原(-)和未还原(-)重组hFGF basic 电泳后考马斯蓝染色过夜。

Western Blotting

Western Blotting

Western blot analysis of extracts from NIH/3T3 cells, untreated or treated with Human Basic Fibroblast Growth Factor for 10 minutes, using Phospho-CREB (Ser133) Antibody #9191 (upper) and CREB Antibody #9192 (lower).用Phospho-CREB (Ser133) 抗体 #9191 (上) and CREB 抗体 #9192 (下)在western blot实验中检测未处理或经人Basic Fibroblast Growth Factor 处理10分钟后NIH/3T3细胞提取物。



The proliferation of NIH/3T3 cells treated with increasing concentrations of hFGF basic was assessed. After 24 hr treatment, cells were labeled with BrdU for 4 hrs. BrdU incorporation was determined by ELISA and the OD450-OD690 was determined.检验浓度逐渐增长的hFGF basic 对NIH/3T3细胞增殖的影响。细胞在孵育24小时后,用BrdU处理4小时。BrdU掺入使用ELISA验证并检验OD450-OD690 。

FGF basic (FGF2) is producted in both embryonic and adult cell types, and contributes to the pathogenesis of various diseases, including cancer and atherosclerosis (1). FGF basic is involved in developmental processes and regulates differentiation, proliferation, and migration (1-6). FGF basic is a critical factor for growing embryonic stem cells in culture without inducing differentiation. FGF basic has a high affinity for heparan sulfate (1,2) and binding is a step in the FGF basic activation of FGFR tyrosine kinase. There are four distinct FGF receptors and each has multiple splice variants. FGF basic binds with high affinity to many, but not all, FGFRs. Signaling cascades activated through FGF basic binding to FGFR include the ras-raf-MAPK, PLCγ/PKC, and PI3K/AKT pathways (1).

胚胎和成体细胞均能生成成纤维细胞因子(FGF basic,FGF2),成纤维细胞因子与各种疾病的发生相关,包括癌症和动脉粥样硬化(1)。FGF2涉及发育过程并且参与调控分化,增殖和转移(1-6)。FGF2是在细胞培养中维持胚胎干细胞的生长而不分化的重要调控因子。FGF2与硫酸肝素有高亲和性(1,2),并且这一结合是FGF2激活FGFR赖氨酸激酶的其中一个步骤。有4个不同的FGF受体,每一个都有多个剪切异构体。FGF2与多个,但不是全部的FGFRs有高亲和性。FGF basic向FGFR的信号传递包括ras-raf-MAPK, PLCγ/PKC, 和PI3K/AKT信号通路(1)。
