  • Synonym
    FGF2,BFGF,FGFB,FGF basic,HBGF-2
  • Source
    Human FGF basic, premium grade(BFF-H4117) is expressed from E. coli cells. It contains AA Pro 143 - Ser 288 (Accession # P09038-4 ).
    Predicted N-terminus: Pro 143
    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

    Less than 0.01 EU per μg by the LAL method.
  • Host Cell Protein
    <0.5 ng/µg of protein tested by ELISA.
  • Host Cell DNA
    <0.02 ng/μg of protein tested by qPCR.
  • Sterility
    The sterility testing was performed by membrane filtration method.
  • Mycoplasma
    Negative.
  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-HPLC.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

  • Background
    FGF basic is a member of the FGF family of at least 23 related mitogenic proteins which show 35-60% amino acid conservation. FGF acidic and basic, unlike the other members of the family, lack signal peptides and are apparently secreted by mechanisms other than the classical protein secretion pathway. FGF basic has been isolated from a number of sources, including neural tissue, pituitary, adrenal cortex, corpus luteum, and placenta. This factor contains four cysteine residues, but reduced FGF basic retains full biological activity, indicating that disulfide bonds are not required for this activity. bFGF is a critical component of human embryonic stem cell culture medium; the growth factor is necessary for the cells to remain in an undifferentiated state, although the mechanisms by which it does this are poorly defined. It has been demonstrated to induce gremlin expression which in turn is known to inhibit the induction of differentiation by bone morphogenetic proteins. It is necessary in mouse-feeder cell dependent culture systems, as well as in feeder and serum-free culture systems.
