|Protein Name||Interleukin-1 beta(IL-1 beta)|
|Molecular Weight||30644 MW|
|Protein Function||Produced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells.|
|Subcellular Localization||Secreted. The lack of a specific hydrophobic segment in the precursor sequence suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.|
|Alternative Names||Interleukin-1 beta;IL-1 beta;Il1b;|

WB: Rat Testis Tissue Lysate at 40ug
Predicted bind size: 31KD
Observed bind size: 35KD
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
