Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
25.4 kDa. Protein migrates as 33-37 kDa in reduced SDS-PAGE resulting from glycosylation
HEK 293 Cells
Greater than 95% by SDS-PAGE
Measured by its binding ability in a functional ELISA. When Folic Acid Bovine Serum Albumin is coated at 5 µg/ml (100 µl/well), the concentration of rhFOLR1 that produces 50% of the optimal binding response is found to be approximately 0.35-1.8 nM.
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from PBS, pH 7.4, mannitol or trehalose
Centrifuge the vial before opening. Reconstitute in sterile PBS, pH 7.4 to 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, store at -20°C.
Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. 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. Required for normal embryonic development and normal cell proliferation.
