Molecular Weight | The recombinant canine IL1B consists of 153 amino acids and has a calculated molecular mass of 17.6 kDa. In SDS-PAGE under reducing conditions, it migrates as an approximately 17 kDa band. |
predicted N | Met |
SDS-PAGE | |
Purity | > 96 % as determined by SDS-PAGE |
Protein Construction | A DNA sequence encoding the mature form of canine IL1B (Q28292) (Ala 115-Ser 266) was expressed, with an initial Met at the N-terminus. |
Bio-activity | 1. Measured by its ability to bind human IL1R1 in a functional ELISA. 2. Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells. The ED50 for this effect is typically 2-12 pg/mL. |
Research Area | Cardiovascular |Atherosclerosis |Vascular Inflammation |Inflammatory mediators |
Formulation | Lyophilized from sterile 20mM PB, 0.3M NaCl, pH 6.5 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
Background | Interleukin-1 beta (IL1 beta or IL1B) also known as catabolin, is a member of the interleukin 1 cytokine family. IL1 is a pleiotropic cytokine. It is involved in the inflammatory response, cell growth, and tissue repair in the cortex. The IL1 superfamily consists of three members, IL1A (IL1 alpha), IL1B (IL1 beta), and IL1 receptor antagonist (IL1Ra). In clinical, it has been reported that Interleukin (IL)-1 may influence Th1 / Th2 immune responsiveness and has been implicated in the establishment of successful pregnancy. Proinflammatory interleukin (IL)-1 gene polymorphisms associated with high levels of IL-1beta activity increase the risk for hypochlorhydria and distal gastric carcinoma. IL1B polymorphisms may be involved in susceptibility to SSc. Moreover, the IL2-384-G allele may be a marker for the limited phenotype of systemic sclerosis (SSc). |
