The present invention relates to a rabbit monoclonal antibody that binds to human Id3 protein and/or mouse Id3 protein with high specificity and high affinity. The antibody has a binding constant, measured with respect to human Id3 protein or mouse Id3, of greater than 1&#xd7;10/molar. The antibody has no substantial cross-reactivity to other family Id proteins such as Id1, Id2, or Id4, or other endogenous proteins present in the cells that express Id3 protein. The specificity and high affinity of the rabbit monoclonal antibodies of the present invention allows sensitive and specific detection and/or quantitation of human or mouse Id3 protein in biological samples. The antibodies are useful in immunochemical-based assays such as ELISA, western blot, and immunohistochemical staining.

Rabbit monoclonal antibodies against mouse/human Id3 proteins

The present invention relates to a rabbit monoclonal antibody that binds to human Id1 protein and/or mouse Id1 protein with high specificity and high affinity. The antibody has a binding constant, measured with respect to human Id1 protein and/or mouse Id1 protein, equal to or greater than 1&#xd7;10/molar. The antibody has no substantial cross-reactivity with other family Id proteins such as Id2, Id3, or Id4, or other endogenous proteins present in the cells that express Id1 protein. The high specificity and high affinity of the rabbit monoclonal antibodies of the present invention allows sensitive and specific detection and/or quantitation of Id1 protein in biological samples. The antibodies are useful in immunochemical-based assays such as ELISA, western blot, and immunohistochemical staining.

A control material for use in the determination of glycosylated and total hemoglobin, and a method of preparing the same, are disclosed. The control is prepared by the steps of hemolyzing red blood cells, preferably in the presence of a detergent, followed by removal of stroma and lipids from the hemoglobin with an organic solvent such as toluene in the presence of a polyhydroxy compound such as sucrose. A hemoglobin-rich fraction is separated from the resulting mixture and dialyzed against a solution of a polyhydroxy compound. The dialysate may be lyophilized to provide a stable, dry product suitable for reconstitution.
