Representative Biological Activity: This product has been reported to have biological activity with an ED50 in the range of 0.2 -0.5ng/ml.
Note: Carrier proteins should be pre-screened for possible effects in an appropriate experimental system. Carrier proteins may effect experimental results due to toxicity, high endotoxin levels or possible blocking activities. - 产品特性
- The recombinant human IL-7 is > 95% pure as determined by SDS-PAGE and an absorbance assay based on the Beers-Lambert law. Endotoxin level is ≤ 0.1 ng per µg of human IL-7, as measured in a chromogenic LAL assay. Recombinant human IL-7 is supplied lyophilized from a solution comprised of 0.22 µm sterile-filtered PBS and containing 50 µg bovine serum albumin per µg of cytokine.

- 应用备注
- ELISA Standard: This recombinant human IL-7 is useful as a quantitative standard for measuring human IL-7 protein levels in an IL-7 specific sandwich ELISA with the purified BVD10-40F6 antibody (Cat. No. 554493) as a capture antibody and the biotinylated BVD10-11C10 (Cat. No. 554494) as the detection antibody. To obtain linear standard curves, doubling dilutions of this human IL-7 standard from ~2,000 to 15 pg/ml should be included in each ELISA plate.

This preparation contains no preservatives, thus it should be handled under aseptic conditions. Store product at -80°C prior to reconstitution, or for long term storage of lyophilized product or reconstituted stock solutions. The product can be reconstituted in sterile neutral buffer containing carrier protein such as human or bovine albumin, aliquoted and stored at -80°C. For in vitro biological assay use, we recommend carrier-protein concentrations of 0.5 - 1 mg/ml. For use as an ELISA standard we recommend carrier-protein concentrations of 5 - 10 mg/ml.
Note: Failure to add carrier protein or store at indicated temperatures may result in a loss of activity. The product should not be diluted to less than 25 µg/ml for long term storage. - 储存条件

- 背景
- Interleukin-7 (IL-7) is a potent lymphoid cell growth factor which affects pre-B, pro-B, and early T cells. It will also affect mature T cells in combination with other factors, such as IL-2. It is encoded by a protein of 152 amino acid residues. Human IL-7 migrates as a protein of 17 kDa when analyzed by SDS-PAGE.
