20120046447 | METHOD FOR PRODUCING CONJUGATE OF THYROXINE AND ALBUMIN - It is an object of the present invention to provide a method for producing a conjugate of thyroxine and albumin with higher purity. The present invention provides a method for producing a conjugate of thyroxine and albumin which comprises: step (a) of converting a carboxyl group in thyroxine having a carboxyl group to be linked to albumin into an active ester and allowing the thyroxine to react with albumin, so as to prepare a conjugate of thyroxine and albumin; and step (b) of purifying the conjugate with the use of an acidic mixed aqueous solvent in which the thyroxine having a carboxyl group to be linked to albumin is dissolved but albumin is not precipitated. | 02-23-2012 |
20130052666 | ANTIBODY AGAINST HUMAN TSH AND CANINE TSH - It is an object of the present invention to provide an antibody that recognizes a canine TSH and binds thereto, without obtaining a large amount of canine TSH antigen. The present invention provides a monoclonal antibody produced by a hybridoma having Accession No. FERM BP-11490. | 02-28-2013 |
