Article Abstract

Aim: To analyze YZ-2, a novel protein associated with cerebral ischemia and prepares its polyclonal antibody.

Methods: According to the bioinformatics analysis and prediction of the possible high structure, hydrophilicity and antigenicity of YZ-2, a 22-amino acid residue partial peptide of YZ-2 was synthesized. The synthesized peptide was then used to immunize. And the properties of anti-YZ2 were analyzed by ELISA and Western blot.

Results: The hydrophilicity and antigenicity were predicted by methods of bioinformatics. The polyclonal antibody of YZ-2 was successfully obtained and its specificity and sensitivity were conformed by ELISA and Western blot.

Conclusion: By the bioinformatics analysis and prediction, the hydrophilicity and antigenicity of YZ2 were analyzed. The antibody of YZ-2 was successfully obtained.

For purpose of overcoming the negative impact of high-dose phenols on meat quality, xanthan gum (XG), a natural anionic polysaccharide, was employed to prevent the undesirable interaction between myofibrillar protein (MP) and gallic acid (GA, 150 μmol/g) and ameliorate the gel and emulsification characteristics of MP. XG dose-dependently alleviated the structural damage of MP caused by GA and reduced protein aggregation, manifested as the decrease in surface hydrophobicity, turbidity and aggregate size (p < 0.05) and increase in α-helix content and intrinsic fluorescence.

This immunoinformatics-based study utilized a suite of online predictive tools to characterize the structural and immunogenic properties of rhoptry neck proteins (TgRONs). Full-length amino acid sequences of TgRON2, TgRON4, TgRON4L1, TgRON5, TgRON8, TgRON9, TgRON10, and TgRON13 were retrieved from ToxoDB and subjected to comprehensive analysis. Except for TgRON4L1, all proteins were predicted to be possess antigenic potential, with none identified as allergenic.

In Nigeria, hepatitis B virus (HBV) infection remains a significant public health issue. The emergence of immune escape mutants (IEMs), basal core promoters, and precore (BCP/PC) mutants among asymptomatic individuals has enabled the continuous evolution of the virus in the country. In this study, we used Sanger sequencing of the S gene and the BCP/PC region to investigate the genetic diversity, phylogenetic relationships, and mutational profiles of HBV strains detected in two regions in Nigeria.

A sensitive analysis for self-carried biomarkers of tumor cells is of great significance for early tumor diagnosis and following treatment monitoring. In this work, open microfluidics combined with mass spectrometry for Epithelial cell adhesion molecule (EpCAM) analysis using DNA-mediated rolling circle amplification (RCA) was proposed. Following aptamer binding, the EpCAM signal was amplified and hybridized with a short DNA probe, which could be released by extracting with a denaturant agent and detected via mass spectrometry.
