Structure and immune expression analysis of hemoglobin genes from the blood clam Tegillarca granosa

Y. B. Bao, Wang, Q., Guo, X. M., and Lin, Z. H., Structure and immune expression analysis of hemoglobin genes from the blood clam Tegillarca granosa, vol. 12, pp. 3110-3123, 2013.

Hemoglobin (Hb) is the major protein component of erythrocytes in animals with red blood, although it can serve additional functions beyond the transport of oxygen. The blood clam (Tegillarca granosa) is one of the few mollusks that has Hb, although the structure and function of molluskan Hbs remain unclear. We characterized two unique and highly compartmentalized blood clam hemoglobin genes, Tg-HbIIA and Tg-HbIIB, at the molecular level.

Description of electrophoretic and chromatographic hemoglobin profile of Rhinoclemmys punctularia

C. R. Bonini-Domingos, Silva, M. B., Romero, R. M., Zamaro, P. J. A., Ondei, L. S., Zago, C. E. S., Moreira, S. B., and Salgado, C. G., Description of electrophoretic and chromatographic hemoglobin profile of Rhinoclemmys punctularia, vol. 6. pp. 415-421, 2007.

Studies of the hemoglobin pattern in Brazilian reptiles are important for determining ecological and phylogenetic relationships, but they are scarce. Peripheral blood samples were obtained from 7 males and 18 females of Rhinoclemmys punctularia. The hematological profile was based on the total hemoglobin and hematocrit values. The hemoglobin profile was obtained using electrophoretic procedures at different pH, isoelectric focusing, globin chain electrophoresis, and HPLC. The hematocrit (31 ± 2%) and total hemoglobin (7.5 ± 0.2 g/dL) values did not indicate gender variations.
