Cynomolgus IL-1 Beta/IL-1F2 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Cynomolgus IL-1 Beta/IL-1F2 Protein is expressed from E.coli with His tag at the C-Terminus. It contains Ala117-Ser268.[Accession | A0A2K5VDC7]

分子量大小(Molecular Weight)

The protein has a predicted MW of 18.33 kDa same as Tris-Bis PAGE result.

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

纯度(Purity)

> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS,100mM L-arginine (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Cynomolgus IL-1 Beta on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Cynomolgus IL-1 Beta is greater than 95% as determined by SEC-HPLC.

SPR Data

Human IL-1 RII, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus IL-1 Beta, His Tag with an affinity constant of 1.40 nM as determined in SPR assay (Biacore T200).

背景(Background)

Interleukin-1 beta (IL-1β) is induced by inflammatory signals in a broad number of immune cell types. IL-1β (and IL-18) are the only cytokines which are processed by caspase-1 after inflammasome-mediated activation. IL-1 signaling activates innate immune cells including antigen presenting cells, and drives polarization of CD4 T cells towards T helper type (Th) 1 and Th17 cells.

分子别名(Synonyms)

Interleukin-1 beta; IL-1 beta; IL1F2; IL1B; IL-1BETA; IL1F2; IL-1β; IL-1 beta; IL-1B ;Interleukin-1 β; IL-1 β; IL-1β; IL-1 β

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
