ABSTRACT
AIM:
To clone and express a human monoclonal anti-D Fab fragment in E. coli and make benefits for the expression of the whole immunoglobulin molecules of anti-D.METHODS:
The gene of anti-D Fab fragment was cloned into the phagemid vector pComb3. After analyzing by PCR and restriction site analysis, the recombinant was expressed in E. coli and the expressed protein was analyzed by SDS-PAGE and ELISA.RESULTS:
The result of SDS-PAGE confirmed that E.coli expressed a 48 kD protein. The ELISA result demonstrated that the cell culture supernatant reacted with Rh+ group O human erythrocytes, but was not recognized by Rh-group O human erythrocytes.CONCLUSION:
Expressed Fab fragment has the antigenic specificity for human erythrocytes.
