Fibroblast Growth Factor-basic (bFGF), also known as FGF-2, is a heparin-binding member of the FGF superfamily of molecules. It plays important role in cell proliferation and differentiation associated with embryogenesis, tissue regeneration, wound healing, CNS development, angiogenesis, and tumor progression.
Traditional Chinese medicine has clinically been proved for its efficacy in cancer treatment, however, its active ingredient is unknown. rh-bFGF was immobilized onto solid supports such as agarose beads for screening compounds interacting with bFGF from traditional Chinese medicine, providing an efficient and rapid technique to identify antineoplastic components from Chinese herb.

Capturing Molecules in interaction with bFGF
1) Equilibrate the prepacked 1 ml column with 5~10 column volumes of 20 mM PBS, pH7.4.
2) Filtrate 10 ml target sample of Tetrastlgma hemsleyanum through a 0.45 レm filter and load the sample.
3) Wash with 5 column volumes of 20 mM PBS, pH7.4.
4) Wash with 4 column volumes of 100 mM sodium glycine, pH 2.7.
5) Discard first 1/3 column volume of elution buffer II and immediately collect 1 column volume of eluant and neutralize collect fractions with neutralization buffer.
6) HSA affinity column was used as a control.
7) Analyze the elute fraction by HPLC to ensure that target molecule is captured (Figure 1).
1) It is easy and simple to use the prepacked column. It is not necessary to need any equipment to capture target molecules.
2) Be sure that the target molecule is stable under the elution conditions selected. If there is any doubt, titrate the elute fraction to neutrality immediately in order not to lose biological activity. For this purpose, prefill the fraction tubes to 5~10% of one column volume with a buffer concentrate at about pH9.0 (for example 1 M Tris-HCl or 1 M sodium phosphate).
3) Make sure temperature of the equilibration buffer identical to that of the packed column to avoid air bubbles. If air bubbles are found in the column, the column should be refilled.
4) It is recommended to regenerate the resin by 4 column volumes of 0.1 M glycine-HCl (pH 2.7) once after 5 times separation cycle in order to extend the column life.
5) After 10 times separation cycle, wash the resin with 5 column volumes of 20% ethanol and 5~10 column volumes of 70% ethanol sequentially to remove hydrophobic substances.
6) For longer periods of storage, keep at 4~8℃ in 20% ethanol.
