Recombinant Human Interleukin-17F (rHuIL-17F) PR1064
Specifications
| 5µg / 25µg / 1.0mg |
Source:
Escherichia coli.
Molecular Weight:
A disulfide-linked homodimer of 30.1kDa, consisting of two 133 amino acid polypeptide chains.
Purity:
>95% by SDS-PAGE and HPLC analyses.
Biological activity:
Measured by its ability to induce IL-6 production by NHDF cells, it’s fully biologically active when compared to standard.

Endotoxin:
Less than 1EU/g of rHuIL-17F as determined by LAL method.
Formulation:
Lyophilized from a 0.2m filtered concentrated solution in PBS, pH 7.4.
Background:
Human IL-17F is synthesized as a 153 aa precursor with a 20 aa signal sequence and a 133 aa mature region. Like IL-17A, IL-17F contains one potential site for N-linked glycosylation. IL-17A and IL-17F share 50% aa sequence identity. IL17-F homodimer is produced by an activated subset of CD4+ T cells, termed Th17. IL17-F has been shown to stimulate proliferation and activation of T-cells and PBMCs. IL-17F also regulates cartilage matrix turnover and inhibits angiogenesis.
Usage:
This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Reconstitution:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 4 mM HCl to a concentration of 0.1mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20C. Further dilutions should be made in appropriate buffered solutions.
Storage:
This lyophilized preparation is stable for several weeks at 2-8C, but should be kept at -20C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20C to -70C. Avoid repeated freeze/thaw cycles.
