Ghrelin, Obestatin, and Nesfatin - NEWLY UPDATED!

Growth hormone releasing peptide 6 (GHRP-6) was the first synthetic peptide that was shown to release growth hormone (GH) and stimulate weight gain by binding to growth hormone secretagogue receptor type 1a (GSR1a)


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.
