Abstract

Characterization of Potato Virus M epitopes with the use of synthetic peptides

Highlights

  • The antigenic analysis of two Potato Virus M Ukrainian strains (PVM Ul and U7) was carried out with the use of three monoclonal antibodies (MAbs M6D5, M9G1 and M4C1) [1]

  • The fractions collected were tested by indirect ELISA using three MAbs, M6D5, M4C1 and M9G1

  • Cognise any thermolysinic fraction while MAbs M6D5 and M9G1 reacted with fraction 17

Summary

Introduction

The antigenic analysis of two Potato Virus M Ukrainian strains (PVM Ul and U7) was carried out with the use of three monoclonal antibodies (MAbs M6D5, M9G1 and M4C1) [1]. The synthetic peptide P14, corresponding to the tryptic fragment 2 Glu-Lys35, inhibited the MAbs M6D5 and M9G1 interaction with In previous work [1 ] we pointed out that lack of reaction between MAb M9G1 and lengthened peptides 22Glu/Gly-Arg44 may be caused by structural changes in the C-terminal region of this fragment after protein cleavage by trypsin.
