For in vitro use only!

Shipping: shipped at ambient temperature

Storage Conditions: store at -20 °C
avoid freeze/thaw cycles

Shelf Life: 12 months

Accession number: O15520

Accession number: O15520

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilized (KGF-2 is lyophilized from a 1 mg/ml solution containing 5 mM Sodium phosphate buffer pH 7.4 and 80 mM NaCl)

Solubility: It is recommended to reconstitute the lyophilized KGF in bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Activity: ED50: < 0.5 ng/ml, corresponding to a specific activity 2 x 106 IU/mg, stimulation of KGF-responsive BaF3 indicator cells (measured by 3H-thymidine uptake).

Keratinocyte growth factor-2 (KGF-2), also described as fibroblast growth factor-10 (FGF-10), is a member of the fibroblast growth factor family. KGF-2 shares 57% sequence homology to KGF-1 (FGF-7). It selectively induces epithelial cell proliferation, differentiation and migration. KGF stimulates the proliferation of primary and secondary human keratinocytes to the same extent as EGF. Recombinant human KGF-2 (FGF-10) produced in E. coli is a single, non-glycosylated polypeptide chain containing 170 amino acids and having a molecular mass of 19.3 kDa. KGF-2 is highly related to KGF-1 (FGF-7), it binds to the same receptor as KGF-1 and shares 57% sequence homology. Recombinant KGF-2 is purified by proprietary chromatographic techniques.
