GRADE & PURITYCarrier 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.Azide Free?Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.≥95%(SDS-PAGE)

Overview
Keratinocyte growth factor (KGF) is a cytokine found by Rubin et al. (1989) from the culture supernatant of embryonic lung fibroblasts, which is a member of the FGF family, namely FGF-7. KGF is an effective epithelial-specific growth factor secreted by mesenchymal cells and distributed in epithelial cells. Its mitotic activity is mainly manifested in keratinocytes, which can specifically promote the proliferation, migration and differentiation of epithelial cells. It is closely related to organ development, wound repair, tumor genesis and immune reconstruction. Activity definition: The ED50 value is less than 1.0 ng/ml, that is, the corresponding activity unit is greater than or equal to 1 x 10*6 units/mg, as determined by the proliferation method of cultured MCF-7 cells.
It is recommended to re dissolve OsrhKGF freeze-dried powder to 100-200 ug/ml with sterile water, and further dilute it with other solvents. The dissolved OsrhKGF can be stored for 2-7 days at 4 ℃ and used up as soon as possible. If it is not used for a short time, please store it at - 20 ℃. After opening, please use it as soon as possible to avoid pollution.
