[Preparation and identification of monoclonal antibody against PNAS-2 protein].
This study was purposed to prepare and primarily identify the specific monoclonal antibodies (McAbs) against the apoptosis related protein PNAS-2 so as to provide the essential tool for study of PNAS-2 function. The McAbs against PNAS-2 were prepared via the immunization of mice, cell fusion and cloning using synthetic peptide of PNAS-2 as immunogen; the specificity, titer and subtype of McAb were detected by Western blot, ELISA and immunofluorescence. The results showed that the stable hybridoma cell line S-31-7 producing McAbs against PNAS-2 protein was successfully obtained. The immunoglobulin of the McAb was identified to be IGg1lambda. The titer of ascetic fluid fled McAb were 1:8,000. A single specific band with 28 kD was shown in Western blot test, and the antigen recognized was present in cell cytoplasm by immunofluorescence. In conclusion, the obtained McAb against PNAS-2 displays strong specificity and high titer, which may be applied to the advanced research on PNAS-2 protein.
