Abstract:
In this study, cytometric beads array(CBA) was used to determine the immunoglobulin content in humoral immunity evaluation of biomedical materials. The bovine-derived acellular dermal matrix was selected as a test sample and implanted into Balb/C mice subcutaneously to 4 weeks according to the high, medium and low dose groups. Four weeks later, IgG1, IgG2a, IgG2b, IgG3, IgA, and IgM were measured by CBA. The data of the test group and the control group were analyzed statistically. The results showed that compared with the negative control group, there was no significant difference in the IgG3, IgA content in the positive control group, while the IgG1, IgG2a, IgG2b, and IgM contents were significantly higher than the negative control group; no significant differences were seen in the sample groups. The results show that the method is suitable for analysis of immunoglobulin content in humoral immunity evaluation of biomedical materials.
