Recombinant Human FLT1 Protein (Ser27-His687), C-Fc and 6×His-tagged

Product Description

Cat

IMP-10125

Official Symbol

FLT1

Product Overview

Recombinant human VEGFR1/Flt-1 protein (Ser27-His687) with a human IgG1 (Pro100-Lys330) Fc tag and 6×His tag at C-terminus was expressed in Spodoptera frugiperda, Sf 21 (baculovirus) cell.

Description

This gene encodes a member of the vascular endothelial growth factor receptor (VEGFR) family. VEGFR family members are receptor tyrosine kinases (RTKs) which contain an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and a tyrosine kinase (TK) domain within the cytoplasmic domain. This protein binds to VEGFR-A, VEGFR-B and placental growth factor and plays an important role in angiogenesis and vasculogenesis. Expression of this receptor is found in vascular endothelial cells, placental trophoblast cells and peripheral blood monocytes. Multiple transcript variants encoding different isoforms have been found for this gene. Isoforms include a full-length transmembrane receptor isoform and shortened, soluble isoforms. The soluble isoforms are associated with the onset of pre-eclampsia.

Form

Lyophilized from a 0.2 μm filtered solution in MOPS, NaCl and CHAPS.

Molecular Mass

Predicted Molecular Mass: 100 kDa (monomer)
SDS-PAGE: 123 kDa, reducing conditions

Protein length

Ser27-His687

Bio-activity

Measured by its ability to inhibit the VEGF-dependent proliferation of HUVEC human umbilical vein endothelial cells. The ED50 for this effect is 5-30 ng/mL.

Endotoxin

<0.10 EU/μg of the protein by the LAL method.

Purity

>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.

Notes

Disulfide-linked homodimer

Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
3 months, 2 to 8 centigrade under sterile conditions after reconstitution.

Reconstitution

Reconstitute at 100 μg/mL in sterile PBS.
