Abstract Preliminary experiments indicate that human erythrocyte membranes contain very large polypeptide chains, of molecular weight about 200,000. This is the second largest molecular weight ever reported for a single polypeptide chain from any mammalian tissue, the only larger one being the heavy chain of myosin.
Gwynne et al. (Mon,) studied this question.
