产品英文概述

Interleukin-1 beta (IL-1β) is a non-secreted proinflammatory cytokine produced mainly by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It possesses metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. Both IL-1alpha and IL-1β binds to the same receptor and has similar but not identical biological properties. Recombinant equine interleukin-1 beta is a 17 kDa protein containing 153 amino acid residues and it shares 63 %~70 % a.a. sequence identity with canine, cotton rat, porcine, feline, human, mouse, rat, and rhesus IL1β.

来源

Escherichia coli.

分子量

Approximately 17.3 kDa, a single non-glycosylated polypeptide chain containing 153 amino acids.

生物活性

Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine D10S cells is less than 20 pg/ml, corresponding to a specific activity of > 5.0 × 107 IU/mg.

外观

Sterile filtered white lyophilized (freeze-dried) powder.

配方

Lyophilized from a 0.2 um filtered concentrated solution in 1 × PBS, pH 7.4, 0.1 % Tween-80.

内毒素

Less than 1 EU/ug of rEqIL-1β as determined by LAL method.

溶解说明

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

储存条件

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
