General description

Product Source: HumanKine growth factors are expressed in a proprietary human 293 protein expression system and are manufactured without the use of any animal products and are considered Xeno-Free.
The HumanKine Thermostable bFGF is engineered with enchanced thermostability compared to the wild-type bFGF protein without modification of biological function.

Fibroblast Growth Factor-basic (bFGF) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. bFGF also exerts a potent angiogenic activity in vivo. Human bFGF is a 17.2 kDa protein containing 154 amino acid residues. bFGF synergizes with the BMP antagonist noggin to sustain undifferentiated proliferation of human embryonic stem (hES) cells under feeder-free conditions.

Application

Engineered bFGF growth factor with enchanced thermostability compared to the wild-type bFGF protein. Allows a less vigorous feeding schedule for human es/ips and neural stem cell culture.

Quality

Bioactivity assay: Determined by the dose-dependent stimulation of the proliferation of the 3T3 cell line. EC50 is typically ≤0.5 ng/mL.

Physical form

Lyophilized from a 0.2 μm filtered solution of 1X PBS.

Storage and Stability

Store at -20°C for up to 4 months from date of receipt. Further dilutions should be made into appropriate buffer or medium to which protein has been added.

HMGB1-RAGE signaling plays an integral role in inflammation-driven carcinogenesis. In the present study, we showed that RAGE has direct association with K-Ras following HMGB1 exposure in colorectal cancer (CRC) cells. Immunofluorescence analysis revealed a significant co-localization between RAGE and K-Ras

The unique characteristics of chicken primordial germ cells (PGCs) provide potential strategies for transgenic animal generation; however, insufficient PGC availability has limited their application. Regulation of bone morphogenic protein 4 (BMP4), a crucial factor for PGCs formation, may provide new

The unique developmental characteristics of chicken primordial germ cells (PGCs) enable them to be used in recovery of endangered bird species, gene editing and the generation of transgenic birds, but the limited number of PGCs greatly limits their application. Studies

Altered neural stem/progenitor cell (NSPC) activity and neurodevelopmental defects are linked to intellectual disability. However, it remains unclear whether altered metabolism, a key regulator of NSPC activity, disrupts human neurogenesis and potentially contributes to cognitive defects. We investigated links between
