分子别名(Synonym)

IL1RL1,DER4,FIT-1,IL33R,ST2,ST2L,ST2V,T1

表达区间及表达系统(Source)

Human IL-1RL1, Fc Tag (IL1-H5250) is expressed from human 293 cells (HEK293). It contains AA Lys 19 - Pro 323 (Accession # NP_003847).

Predicted N-terminus: Lys 19

蛋白结构(Molecular Characterization)

Online(Lys 19 - Pro 323) NP_003847

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 61.0 kDa. The protein migrates as 80-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human IL-1RL1, Fc Tag (Cat. No. IL1-H5250) at 5 μg/mL (100 μL/well) can bind Human IL-33, His Tag (Cat. No. IL3-H52H7) with a linear range of 5-40 ng/mL (QC tested).

Protocol

背景(Background)

Interleukin 1 receptor-like 1 (IL1RL1) is also known as ST2, DER4, FIT-1, IL33R, ST2L, ST2V, which belongs to the interleukin-1 receptor family. IL1RL1 contains three Ig-like C2-type (immunoglobulin-like) domains and one TIR domain. IL1RL1 is receptor for interleukin-33 (IL-33), its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. IL1RL1 possibly involved in helper T-cell function. IL1RL1 can interact with MYD88, IRAK1, IRAK4, and TRAF6.
