PROTEIN HC A low molecular weight plasma protein
Protein HC or alpha-1-microglobulin is a human glycoproteinof low molecular weight (25-30,000) present in plasma, urine and cerebrospinal fluid. It also occurs in association with the surface of various human cell types.The protein, containing only one polypeptide chain, is heterogeneous in charge, even when desialylated, has a marked tendency to form complexes with other plasma proteins, e.g., Ig
