Description_x000D_ General description_x000D_ Hemocyanin is a large, multi-subunit respiratory protein present in arthropods and mollucs. They circulate extracellularly in hemolymph. Hemocyanins do not contain iron but bind oxygen at an active site containing copper atoms ligated by protein side chains._x000D_ Application_x000D_ Anti-Hemocyanin (KLH) antibody produced in rabbit has been used in:_x000D_ • immunocytochemistry{58_x000D_ • }immunohistochemistry_x000D_ • immunofluorescent staining_x000D_ • immunoblotting_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Keyhole limpet hemocyanin has been used traditionally as a protein carrier for hapten-carrier conjugates in immunochemistry. Keyhole limpet hemocyanin (KLH) has been regarded as a superior carrier. Affinity isolated antibody to hemocyanin may be used as a control reagent for the preparation and immunization of hapten-carrier conjugates.
