Immunochemistry Research
Lipolysaccharide of Salmonella Haarlem (9.46) – detection the new OPS composition: 3,9,46 (according to Kauffmann-White scheme).
Epitope analysis of S. Enteritidis isolated flagella antigen and synthetic peptides of hypervariable part of this antigen.
12.04.23 6
Immunological investigations of viruses synthetic peptides.
Hepatitis B Virus:
- X-Gene coded protein fragments;
- surface antigen (140-146) region fragment. Hepatitis C Virus:
- protein fragments
(evaluation of their immunogenicity and
diagnostic propertis in HCV infection)
12.04.23 7
Immunological investigations of heat shock protein fragments.
Human hsp 70 fragment (29-42), and
their cyclic analogue – conformational studies and evaluation of its immunogenicity.
Human hsp 60 fragment (409-424) – is recognized by serum antibodies of patients with acute coronary syndroms.
12.04.23 8
Immunological investigations of heat shock protein.
Characterisation of the anti-DnaJ monoclonal antibodies and their use to compare immunological properties of DnaJ and its human homologue HDJ-1 – epitope analysis of the similar domains of E. coli DnaJ and human HDJ-1 (in cooperation with Prof. B. Lipińska team, UG).

POLYVALENT VACCINE „IMMUNOVAC” AGAINST SALMONELLOSIS IN ANIMALS
„Immunovac” vaccine is composed of several Salmonella serovars and polyclonal antibodies
Generates active and passive immunization after oral administration.
The vaccine is in the course of commercialization by BIOWET in Puławy.

IMMUNOLOGICAL INVESTIGATIONS OF PORPHYRIN DERIVATIVES
Porphyrines and their amino acids derivatives • PP(FAla)2Arg2• PP(Ala)2Arg2• PP(Ser)2Arg2 and their mixture (Sensifirine)are intended to be used in PDT (photodynamic therapy).Our goal is to investigate their impact on the immune system. The researches are performed in cooperation with the teams of prof. Alfreda Graczyk (MUT, Warsaw) and prof. Anna Podhajska ( MBW AMG-UG, Gdańsk)
