BACKGROUND AND OBJECTIVE: Neisseria meningitidis is a leading cause of meningitis
and sepsis worldwide. The factor H binding protein (fHBP) is a key virulence
factor of Neisseria meningitidis that is able to selectively bind to human factor
H, the key regulator of the alternative complement pathway, which it has
important implications for meningococcal pathogenesis and vaccine design. The
aims of present research were cloning, expression, purification of fHbp and
confirmation of the interaction between serum factor H (fH) and produced factor H
binding protein. MATERIALS AND METHODS: A 820 base pairs fhbp gene fragment was
amplified by PCR and cloned into expression vector pET28a (+) in Bam HI and SalI
restriction enzymes sites. Recombinant DNA was expressed in BL21 (DE3) cell. fHBP
protein was purified by Ni-NTA agarose resin. Coupling of recombinant protein
into CNBr activated Sepharose 4B resin was carried out for application in serum
fH protein purification. (fH-fHBP) interaction was confirmed by SDS-PAGE and
far-western blotting. RESULTS AND CONCLUSIONS: SDS-PAGE results showed a 35 kDa
protein band. 150 kDa fH protein was purified by designed Sepharose 4B resin.
Far-western blotting confirmed (fH-fHBP) interaction and proper folding of factor
H binding protein.
