GONGORA AMORES, Walter et al. Rabbit serum with complement activity to typify human major histocompatibility complex. Rev Cubana Invest Bioméd [online]. 2012, vol.31, n.1, pp. 81-86. ISSN 0864-0300.

Microlinfocitotoxicity assay is one of the serological methods used to classify human major histocompatibility complex. In this technique the rabbit´s serum as complement source, plays an essential role in antigens determination and in lymphocytes cross match assay as necessary stage before the selection of the best donor-receiver pair to realize the organ transplant. Three experimental lots of normal rabbit serum were developed with excellent indicators of efficiency, biological activity and stability. Rabbit's blood was obtained through jugulating technique and serum was separated by centrifugation in controlled environment and temperature´s conditions. The sterilization process was performed by filtration and the samples were taken for quality´s control assays. Stability studies showed that the product kept the biological activity at least during 18 months after it was processed and cytotoxicity's values were adequate for its employment in histocompatibility pre-transplant assays.

Keywords : rabbit serum; complement activity; HLA typing; serological method; microlinfocitotoxicity; organ transplant.
