Function
Folate receptor 1 (Folate receptor alpha, FOLR1) is a protein that in humans is encoded by the FOLR1 gene. The protein encoded by this gene is a member of the folate receptor (FOLR) family. Members of this family have a high affinity for folic acid and for several reduced folic acid derivatives, and mediate delivery of 5-methyltetrahydrofolate to the interior of cells. This receptor is responsible for binding to folic acid and its derivatives, which becomes crucial during fetal development. By adding folate supplementation during pregnancy, neural tube defects in the fetus are prevented. Folate derivatives are necessary for important metabolic processes such as DNA, protein and lipid methylation. More importantly, folate plays a major role in DNA replication and cell division, which are common characteristics of rapid growth. Even though it is unclear how folate affects neural tube formation, scientists are certain that without appropriate folate levels, neural tube defects can develop through human and mice studies. Neural tube defects refer to the improper development of the neural tube by not being sealed correctly. This results in exencephaly or spina bifida, both nervous system abnormalities. This gene is composed of 7 exons; exons 1 through 4 encode the 5' UTR and exons 4 through 7 encode the open reading frame. Due to the presence of 2 promoters, multiple transcription start sites, and alternative splicing of exons, several transcript variants are derived from this gene. These variants differ in the lengths of 5' and 3' UTR, but they encode an identical amino acid sequence.

Exposure time: 1 minute; ECL: K1801;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA751117) at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature. -
Immunohistochemical analysis of paraffin-embedded human ovary cancer tissue with Rabbit anti-FOLR1 antibody (HA751117) at 1/200 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA751117) at 1/200 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -
☑ Relative expression (RE)
Flow cytometric analysis of MDA-MB-231 (left, negative) and HeLa (right, positive) cells labeling FOLR1.
Cells were fixed and permeabilized. Then stained with the primary antibody (HA751117, 1/1,000) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody (HA1121) at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
