FOLR1 in HeLa Human Cell Line. FOLR1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Mouse FOLR1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6936) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

FOLR1 in Mouse Kidney. FOLR1 was detected in perfusion fixed frozen sections of mouse kidney using Sheep Anti-Mouse FOLR1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6936) at 0.3 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to convoluted tubules.

Background: FOLR1

Folate receptor 1 (FOLR1; also folate receptor alpha and folate binding protein 1/FOLBP1) is a 40-50 kDa member of the folate receptor family. FOLR1 is expressed in reticulocytes, retinal Muller cells and placenta, plus renal, mammary and thymic epithelium, where it mediates the transport of 5-methyltetrahydrofolate into the cell. The mouse FOLR1 preproprecursor is 255 amino acid (aa) in length. It contains a GPI-linked glycoprotein that is 208 aa in size (aa 25-232), and which possesses three potential N-linked glycosylation sites. There is one potential isoform variant that shows a 105 aa substitution for aa 110-255. Over aa 23-232, mouse FOLR1 shares 83% and 93% aa sequence identity with human and rat FOLR1, respectively.
