Related Product Information for anti-FOLR1 antibody
FOLR1 is a 37-42kD protein that mediates the cellular uptake of folic acid and reduced folates. Dietary folates are required for many key metabolic processes including nucleotide and methionine synthesis, the interconversion of glycine and serine and histidine breakdown. Mature FOLR1 is an N-glycosylated protein that is anchored to the cell surface by a GPI linkage. Human FOLR1 shares 83% amino acid sequence identity with mouse and rat FOLR1. FOLR1 is predominantly expressed on epithelial cells and is dramatically up- regulated on many carcinomas. It is critically required during early embryogenesis as shown in knockout mice which die in utero with gross morphological defects. FOLR1 is internalized to the endosomal system where it dissociates from its ligand before recycling to the cell surface. A soluble form of FOLR1 can be proteolytically shed from the cell surface into the serum and breast milk.

NCBI Description

The protein encoded by this gene is a member of the folate receptor family. Members of this gene family bind folic acid and its reduced derivatives, and transport 5-methyltetrahydrofolate into cells. This gene product is a secreted protein that either anchors to membranes via a glycosyl-phosphatidylinositol linkage or exists in a soluble form. Mutations in this gene have been associated with neurodegeneration due to cerebral folate transport deficiency. Due to the presence of two promoters, multiple transcription start sites, and alternative splicing, multiple transcript variants encoding the same protein have been found for this gene.

Uniprot Description

FOLR1: Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate to the interior of cells. Defects in FOLR1 are the cause of neurodegeneration due to cerebral folate transport deficiency (NCFTD). NCFTD is an autosomal recessive disorder resulting from brain- specific folate deficiency early in life. Onset is apparent in late infancy with severe developmental regression, movement disturbances, epilepsy, and leukodystrophy. Recognition and diagnosis of this disorder is critical because folinic acid therapy can reverse the clinical symptoms and improve brain abnormalities and function. Belongs to the folate receptor family.

The FOLR1 (Folate receptor 1 (adult) Adult folate-binding protein, FBP, Folate receptor, adult, Folate receptor 1, Folate receptor alpha, FOLR, FR-alpha, KB cells FBP, MOv18, Ovarian tumor-associated antigen MOv18) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's FOLR1 can be used in a range of immunoassay formats including, but not limited to, Suitable for use in ELISA, Flow Cytometry, Western Blot and Immunocytochemistry. Other applications not tested. Recommended Dilution: ELISA (Capture): 2-8ug/ml Flow Cytometry: 0.25ug labels/10e6 cells. Tested in MCF-7 cells. Western Blot: 2ug/ml detects human FOLR1 in human cortex tissue and HeLa cells under non-reducing conditions only. Immunocytochemistry: 8-25ug/ml. Tested on immersion fixed MCF-7 cells. Optimal dilutions to be determined by the researcher. Researchers should empirically determine the suitability of the FOLR1 folr1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "FOLR1, Monoclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
