Through the example of the distribution of PCR products DNA matrices of mouse tail tissue, a method of comparative analysis of DNA fingerprints is described. The PCR products were obtained using a 20-mer random primer flanking the Atp1b2 locus on mouse chromosome 11. A software program was designed that permits the simplification of comparison of DNA fragments variability or polymorphism detected on electrophoregrams from different individuals.

Site-directed mutagenesis is a fundamental tool indispensable for protein and plasmid engineering. An important technological question is how to achieve the efficiency at the ideal level of 100%. Based on complementary primer pairs, the QuickChange method has been widely used, but it requires significant improvements due to its low efficiency and frequent unwanted mutations.

Vibrio anguillarum is a pathogen responsible for vibriosis in aquaculture animals. The formation of bacterial biofilm contributes to infections and increases resistance to antibiotics. Tryptophanase and its substrate tryptophan have been recognized as signal molecules regulating bacterial biofilm formation.

Lincomycin, produced by the actinomycete Streptomyces lincolnensis, is highly effective against Gram-positive bacteria and protozoans, making it widely used in clinical settings. This study identified LcbR2, a MarR family transcriptional regulator, as an activator of lincomycin biosynthesis. Knocking out the lcbR2 gene reduced lincomycin production by 63.

Background: Methylglyoxal (MGO), a highly reactive precursor of advanced glycation end products (AGEs), is endogenously produced and prevalent in various ultra-processed foods. MGO has emerged as a significant precursor implicated in the pathogenesis of type 2 diabetes and neurodegenerative diseases. To date, the effects of dietary MGO on the intestine have been limited explored.
