CAS: 62031-54-3 Cat. No.: rp145939 Molecular Weight: 17kD
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. PBS Only ? PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers. ≥95%(SDS-PAGE)

Overview

Recombinant human basic fibroblast growth factor (also known as basic FGF, bFGF, FGF2, FGF-beta, or heparin-binding growth factor), is a biologically active protein suitable for cell culture applications. bFGF regulates diverse processes such as cell proliferation, differentiation, survival, adhesion, motility, apoptosis, limb formation, and wound recovery. bFGF can be used in studies of angiogenesis, fibroblast mitosis, axonal outgrowth in PC-12 cells, receptor binding, and tyrosine phosphorylation. This strain is expressed in recombinant Escherichia coli, and after multi-step separation and purification, it is dissolved in 10mM PBS, 0.15 M NaCl (pH7.2) solution, filtered through a 0.22 μm filter membrane, and then freeze-dried to make a lyophilized powder.

Reconstitution
It is recommended to briefly centrifuge before opening the cap to make the powder sink to the bottom of the tube, then dissolve it in sterilized deionized water to prepare a 100μg/ml stock solution, which can be stored stably for one week at 2°C ~ 8°C. When diluting to a lower concentration (not lower than 10μg/ml), 0.1% tissue culture grade BSA or HSA needs to be added. If extended storage time is required, it is recommended to freeze at -80°C or -20°C, repeated freezing and thawing is not recommended.
Storage
Store at -20°C,Avoid repeated freezing and thawing
Shipped In

Stability And Storage
Store at 2-8℃ short term (4 weeks). Store at -20℃ long term (24 months). Upon reconstitution, it is recommended to aliquot. Avoid freeze/thaw cycle.
