Diabetes is a prevalent disease, ffecting approximately 30.3million Americans (9.4% of the population).


Activated KLH has a large molecular mass and high immunogenic properties that are ideal for immunogenic stimulation. Small peptides containing free sulfhydryl groups can react with Maleimide groups of this carrier protein to form stable thioether bonds. Such carrier peptide conjugates can be used to stimulate antibodies for immunization.
