Description
Recombinant Human Folate Receptor Alpha is produced by our Mammalian expression system and the target gene encoding Arg25-Ser234 is expressed with a 6His tag at the C-terminus.
Accession
P15328
Molecular weight
25.7 KDa
Apparent molecular weight
28-38 KDa, reducing conditions
Other names
Folate receptor alpha;FR-alpha;Adult folate-binding protein;FBP;Folate receptor 1;Folate receptor;Ovarian tumor-associated antigen MOv18;FOLR1
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Biological activity
Immobilized Human FOLR1-His(Cat#C784) at 1μg/ml (100 μl/well)can bind Anti-Human FOLR1 mAb(Cat#NC072).The ED50 of Anti-Human FOLR1 mAb(Cat#NC072)is 0.626 ng/ml.
Redissolve
Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Storage
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Delivery condition
The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
Folate receptor alpha(FOLR) belongs to the folate receptor family, and is primarily expressed in tissues of epithelial origin. It is also expressed in kidney, lung and cerebellum. The secreted form is derived from the membrane-bound form either by cleavage of the GPI anchor, or/and by proteolysis catalyzed by a metalloprotease. FOLR1 binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. It has high affinity for folate and folic acid analogs at neutral pH. Exposure to slightly acidic pH after receptor endocytosis triggers a conformation change that strongly reduces its affinity for folates and mediates their release. It is required for normal embryonic development and normal cell proliferation.
