In male C57Bl/6 mice with transplanted Ehrlich carcinoma, hemoglobin forms a complex with serum proteins characterized by a molecular weight of about 300 kDa. The complex incorporates proteins weighing 100, 68, 65, and 15 kDa identified by MALDI-TOF mass spectrometry as haptoglobin, serum albumin, gi/26341396 nameless protein Mus musculus, and alpha-hemoglobin, respectively. This complex can possess biological activity and contribute to the control of tumor growth.
