RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.


Monoclonal Anti-Folic Acid Antibody



CLONE: 8/39 is derived by hybridisation of NSO myeloma cell line with splenic lymphocytes from BALB/c mouse immunized with tetrahydrofolic acid conjugated to Keyhole Limpet Haemocyanin


SOURCE: Mouse ascitic fluid

PURIFICATION METHOD: Protein A affinity chromatography

SPECIFICITY: Characterisation by ELISA using antigen conjugated to BSA as solid phase antigen. The table shows the absorbance values from ELISA analysis for cross-reactivity with a variety of antigens. The greater the absorbance value the greater the relative affinity of the antibody for that metabolite.

PRESENTATION: Each monoclonal is delivered in a sealed vial at a concentration of 1mg in phosphate buffered saline containing 10mM sodium azide. We recommend that each laboratory determine an optimum working titre for use in its particular application.

STORAGE: Purified monoclonal antibodies are generally stable for long periods at 4oC. However repeated warming to room temperature and re-cooling may result in a loss of activity and hence effective working titre. It is recommended that monoclonal antibodies are aliquotted upon receipt and then stored at -20C. After thawing they should then be used as a stock solution for up to 60 days. Dilute working solutions are best prepared on the day of use.
