Overview
General Description
Recombinant Human IGFBP-3 Protein is expressed from HEK293 with His tag at the C-terminal.It contains Gly28-Lys291.
Biotinylated
Specifications
Target
IGFBP-3
Synonyms
IBP3 ; IGFBP3 ; IGFBP-3 ; BP-53
Accession
Species
Human
Exact Sequence
Gly28-Lys291
Molecular Weight
The protein has a predicted MW of 29.8 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on Tris-Bis PAGE result.

Immobilized Human IGFBP-3, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human IGF-II, hFc Tag with the EC50 of 0.14ug/ml determined by ELISA (QC Test). The affinity constant of 2.32 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag
C-His
Express System
HEK293
Purity
> 95% as determined by Tris-Bis PAGE
Endotoxin
Less than 1EU per ug by the LAL method.
Shipping, Reconstitution & Storage
Appearance
Lyophilized
Shipping Conditions
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & Storage
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
