ABSTRACT
Objective:
To screen the antagonist of C5a anaphylatoxin,and further to study the dinetic characteristics of interaction between C5a and its anti-sense peptides.Methods:
The anti-sense peptides were screened that can interact with C5a selectively by means of dinetic analysis,via biosensor technique.Results:
There is one piece of anti-sense peptide(R4) being screened from these four synthesized peptides.The dissociation equilibrium constant(K D) between R4 and the immobilized hC5a is 6.62?10 -6 mol/L and the K D between R4 and L2 is 7.02?10 -7 .Conclusion:
Based on the results obtained,it was concluded that the optic biosensor is a ideal and powerful tool to facilitate the kinetic analysis of interaction between sense peptide and its anti-sense peptide and to screen antagonist of biologic activity molecule.
