Biological Activity: The activity range is measured in a proliferation assay using TF-1 indicator cells.
Specific Activity Range: 1.0-4.0x10^8 Units /mg
ED50: 25-100 pg/ml
Observed dose response: 100 fold
The Unit is defined as the amount of material required to stimulate a half-maximal response at cytokine saturation. - 产品特性
- Recombinant human IL-1beta is lyophilized from a solution comprised of 0.22 µm sterile-filtered aqueous buffered solution with no preservatives. Each vial contains 250 µg of bovine serum albumin, for a final ratio of carrier protein to human IL-1beta of 50:1. The recombinant human IL-1beta is ≥ 95% pure as determined by SDS-PAGE analysis, and an absorbance assay based on the Beers-Lambert law.
- 纯化方法
- This is the mature form of human IL-1β, a 17 kD protein containing 153 amino acid residues, representing amino acids A117 through S269 of the IL-1β precursor protein, expressed in E. coli. Recombinant human IL-1β is lyophilized from a solution comprised of 0.22 μm sterile-filtered aqueous buffered solution with no preservatives. Recombinant human IL-1β is ≥ 95 % pure as determined by SDS-PAGE, and an absorbance assay based on the Beers-Lambert law.

- 注意事项
- This preparation contains no preservatives, thus it should be handled under aseptic conditions. The product can be reconstituted in sterile neutral buffer containing 0.5 - 10 mg/ml carrier protein such as human or bovine serum 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. Failure to add carrier protein or store at indicated temperatures may result in a loss of activity. Carrier proteins should be pre-screened for possible effects in an appropriate experimental system. Carrier proteins may affect experimental results due to toxicity, high endotoxin levels or possible blocking activity.
- 储存条件
- -80 °C
- 储存方法
- Store product at -80°C prior to use or for long term storage of stock solutions. This preparation contains no preservatives, thus it should be handled under aseptic conditions.
