Vascular Endothelial Growth Factor Receptor-1 D4 Human Recombinant ( FLT1 D4 Human )

Data sheet

Formulation

FLT1 D1-4 was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives.

Solubility

It is recommended to reconstitute the lyophilized FLT1 D4 in sterile water not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 90.0% as determined by(a)Analysis by RP-HPLC.(b)Analysis by SDS-PAGE.

Description

Soluble FLT1 D1-4 Human Recombinant produced in baculovirus is monomeric, glycosylated, polypeptide containing 457 amino acids and having a molecular mass of 55 kDa. The soluble receptor protein contains only the first 4 extracellular domains, which conta

Protein Background

Endothelial cells express three different vascular endothelial growth factor (VEGF) receptors, belonging to the family of receptor tyrosine kinases (RTKs). They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), VEGFR-3 (Flt-4). Their expression is almost ex

Expression host

Insect Cells.

Synonyms

FLT-1, FLT1, Tyrosine-protein kinase receptor FLT, Flt-1, Tyrosine-protein kinase FRT, Fms-like tyrosine kinase 1, VEGFR-1.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized FLT-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FLT1 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a c

Biological Activity

The activity of FLT1D1-4 was determined by its ability to abolish the binding of iodinated VEGF to solid surfaces or cell surfaces, and in Far-Western and cross-linking experiments with iodinated VEGF.

Immunological tests

Binds IgG- and IgA-type human autoantibodies associated with celiac disease.

Shipping Conditions

Standard ELISA test (checkerboard analysis of positive/negative sera panels); immunodot.
