Reactive polypeptide (Specificity): Human 62 kD (p62) protein, present in intracytoplasmic inclusions (e.g. hyaline bodies) of hepatocellular carcinoma. p62 protein has been found in many tissues and cells, including lymphoid cells, serving probably a common cellular signal transduction mechanism. The antiserum stains also neurofibrillary tangles in the brain of patients suffering from Alzheimer’s disease.
