Аннотация: The dynamics of the amino acid composition of the medium was investigated during perfusion of the dog liver and kidney for 6 h with a mixture of autogenous plasma and medium No.199 in the ratio of 2:3. During culture of the kidney for 6 h the histidine concentration in the medium increased by 2.2 times compared with initially, the concentration of glutamic acid by 1.7 times, and of alanine and lysine by 1.6 times, whereas the concentrations of arginine, serine, and aspartic acid fell by 3.3 times and those of glutamine with threonine by 2.5 times. During perfusion of the liver the concentration of glutamic acid rose by 2.9 times, of alanine by 2.3 times, cystine by 2.0 times, and glycine by 1.5 times. The concentration of tyrosine fell by half, and that of phenylalanine and serine by 1.4 times. The arginine concentration fell so quickly during perfusion of the liver that by the second hour after the beginning of perfusion no arginine could be found in the medium. The method of amino acid analysis during organ culture as described can be used as a method of developing and correcting culture media.

    Dynamics of amino acid composition of the medium in isolated organ culture by the controlled perfusion method / V. A. Barashkov [et al.] // Bulletin of Experimental Biology and Medicine. - 1975. - Vol. 80, Is. 7. - P759-761 . - ISSN 0007-4888

Аннотация: The dynamics of the amino acid composition of the perfusion fluid was investigated during adequate perfusion of isolated dog organs (the thorax and a complex consisting of the thoracic organs, kidneys, and liver). The concentration of amino acids such as histidine, lysine, and alanine in the perfusion fluid 6 h after the beginning of perfusion of the organ complex was higher, whereas that of arginine, serine, aspartic acid, threonine with glutamine, isoleucine, proline, leucine, and valine was much lower than initially. In experiments on the isolated thorax the dynamics of the amino acid composition of the medium was studied during perfusion for 4 h. The concentration of alanine, lysine, and histidine in the medium increased, whereas those of serine, aspartic acid, isoleucine, tyrosine, and phenylalanine decreased.

    Study of the immunogenicity of the VP2 protein of canine parvovirus produced using an improved Baculovirus expression system / D. Chang, Y. Liu, Y. Chen [et al.] // BMC Vet. Res. - 2020. - Vol. 16, Is. 1. - Ст. 202, DOI 10.1186/s12917-020-02422-3 . - ISSN 1746-6148

Аннотация: Background: Canine parvovirus (CPV) is now recognized as a serious threat to the dog breeding industry worldwide. Currently used CPV vaccines all have their specific drawbacks, prompting a search for alternative safe and effective vaccination strategies such as subunit vaccine. VP2 protein is the major antigen targeted for developing CPV subunit vaccine, however, its production in baculovirus expression system remains challenging due to the insufficient yield. Therefore, our study aims to increase the VP2 protein production by using an improved baculovirus expression system and to evaluate the immunogenicity of the purified VP2 protein in mice. Results: The results showed that high-level expression of the full length VP2 protein was achieved using our modified baculovirus expression system. The recombinant virus carrying two copies of VP2 gene showed the highest expression level, with a productivity of 186 mg/L, which is about 1.4-1.6 fold that of the recombinant viruses carrying only one copy. The purified protein reacted with Mouse anti-His tag monoclonal antibody and Rabbit anti-VP2 polyclonal antibody. BALB/c mice were intramuscularly immunized with purified VP2 protein twice at 2 week intervals. After vaccination, VP2 protein could induce the mice produce high level of hemagglutination inhibition antibodies. Conclusions: Full length CPV VP2 protein was expressed at high level and purified efficiently. Moreover, it stimulated mice to produce high level of antibodies with hemmaglutination inhibition properties. The VP2 protein expressed in this study could be used as a putative economic and efficient subunit vaccine against CPV infection. © 2020 The Author(s).
