| CYT-219 | 重组人角蛋白生长因子（rHuKGF） | 2μg/10μg/1mg | Prospec |
| Background: | |
| KGF is a potent specific mitogen for many epithelial cells but not for fibroblasts and endothelial cells. KGF is thought to play an important role in the paracrine growth control of normal epithelial cells. KGF stimulates the proliferation of primary and secondary human keratinocytes to the same extent as EGF.
|
|
| Description : | |
| Recombinant Human KGF-1 （FGF-7） produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 164 amino acids and having a molecular mass of 18995 Dalton.
Recombinant KGF is purified by proprietary chromatographic techniques.
|
|
| Physical Appearance: | |
| Sterile Filtered White lyophilized （freeze-dried） powder.
|
|
| Formulation: | |
| Recombinant KGF was lyophilized from a concentrated （1mg/ml） solution with no additives.
|
|
| Solubility: | |
| It is recommended to reconstitute the lyophilized KGF in sterile 18Mω-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
|
|
| Stability: |
|
| Lyophilized KGF although stable at room temperature for 3 weeks, should be stored desiccated below -18 C. Upon reconstitution KGF should be stored at 4 C between 2-7 days and for future use below -18 C. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please avoid freeze-thaw cycles.
|
|
| Purity: | |
| Greater than 98.0% as determined by: （a） Analysis by RP-HPLC. （b） Anion-exchange FPLC. （c） Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
|
|
| Amino acid sequence: | |
| The sequence of the first five N-terminal amino acids was determined and was found to be Met-Cys-Asn-Asp-Met.
|
|
| Dimers and aggregates: | |
| Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
|
|
| Biological Activity: | |
| ProSpec's KGF is fully biologically active when compared to standards. The ED50, calculated by the dose-dependant stimulation of KGF-responsive BaF3 indicator cells （measured by 3H-thymidine uptake） is < 10ng/ml corresponding to a specific activity of 10 Units/mg.
ProSpec's rHuKGF biological activity was measured by the KGF's mitogenic activity on BaF3 cells expressing the KGF receptor.
|
|
| Endotoxin: | |
| Less than 0.1 ng/µg （IEU/µg） of KGF.
|
|
| Protein content: | |
| Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.9 as the extinction coefficient for a 0.1% （1mg/ml） solution. This value is calculated by the PC GENE computer analysis program of protein sequences （InliGenetics）.
