Folate Receptor (FR)

Folate Receptor (FR)

Folate receptor (FR) is a class of cysteine-rich glycosylphosphatidylinositol-coupled protein that can mediate folate transport from outside to inside cells, and is divided into FR-α, FR-β, and FR-γ Subtypes. FR-α is expressed in renal proximal tubules and in various solid epithelial neoplasms (ovary, endometrium, brain, lung, and renal cancers). FR-β is expressed in normal hematopoietic tissue, activated macrophages, and hematogenous malignancies. Folate receptor can be used for the early diagnosis and study of tumors[1]sup>[2].

  • HY-13616
    Etarfolatide
    Etarfolatide (EC 20) is a valuable noninvasive imaging agent. Etarfolatide identifies folate receptor expression. Etarfolatide can be used in research on ovarian cancer and disease diagnosis after being radiolabeled.

  • HY-P992004
    KHK2805
    		Inhibitor
    KHK2805 (RA15-7) is a humanized antibody against folate receptor α (FOLR1), with a Kd of 0.647 nM for human FOLR1. KHK2805 binds to a unique epitope of FOLR1 and mediates antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity against FOLR1-expressing cells. KHK2805 exhibits cytotoxicity against both ovarian cancer cells and Platinum (HY-W096169D)-resistant ovarian cancer cells. KHK2805 can be used for the research of tumors such as ovarian cancer.

    DBCO-PEG5000-FA
    		Ligand
    DBCO-PEG5000-FA (DBCO-PEG5000-Folate) is a multifunctional bioconjugation reagent, which is a copolymer of DBCO and Folic acid (FA) (HY-16637) and can target folate receptors (FR). Folate receptors are highly overexpressed on the surface of many cancer cells (such as lung cancer, nasopharyngeal cancer, ovarian cancer, etc.), but exhibit extremely low expression levels in normal tissues. DBCO-PEG-FA can be used for click chemistry conjugation via its DBCO terminal, and thus applies to various bioconjugation and drug delivery applications.

  • HY-W713855
    (4-Aminobenzoyl)-D-glutamic acid
    		Antagonist
    (4-Aminobenzoyl)-D-glutamic acid (Compound 17) exhibits competitive inhibitory activity against H2-pteroate synthesis system, which affects the synthesis of folate, thereby inhibiting growth of bacteria.
    (4-Aminobenzoyl)-D-glutamic acid
  • HY-D2523
    Cy3-PEG2000-FA
    		Modulator
    Cy3-PEG2000-FA is a fluorescent folate-PEG derivative with excitation/emission wavelengths of ~550 nm/~570 nm. Cy3-PEG2000-FA can be readily traced by its intense red fluorescent signal. Cy3-PEG2000-FA can be used for cell imaging, folate receptor targeting and detection.
