Synonyms

folate receptor 4 (delta) homolog (mouse), Folbp3, FOLR4, FR-delta, LOC390243, probable folate receptor delta

Source

Human FOLR4, His Tag (FO4-H52H3) is expressed from human 293 cells (HEK293). It contains AA Gly 20 - Ser 228 (Accession # A6ND01-1).

Predicted N-terminus: Gly 20

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

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

The protein has a calculated MW of 25.8 kDa. The protein migrates as 30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 500 mM NaCl, pH7.5 with trehalose as protectant.
