蛋白结构(Molecular Characterization)

IGFBP-1 Structure

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 27.2 kDa. The protein migrates as 32-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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)

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Report

 

活性(Bioactivity)-ELISA

IGFBP-1 ELISA

Immobilized Human IGF-I, Fc Tag at 5 μg/mL (100 μL/well) can bind Human IGFBP-1 Protein, His Tag (Cat. No. IG1-H52H3) with a linear range of 0.01-0.156 μg/mL (QC tested).

Protocol

 

背景(Background)

Insulin-like growth factor-binding protein 1 (IGFBP1) is also known as placental protein 12 (PP12), which contains oneIGFBP N-terminal domain and one thyroglobulin type-1 domain. IGFBP1 can bindd both insulin-like growth factors (IGFs) I and II and circulates in the plasma. Binding of IGFBP1 can prolongd the half-life of the IGFs and alterd their interaction with cell surface receptors. Furthermore, IGFBP1 can promote cell migration. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
