Background: Usage of sexed semen that allows to choose the gender of the calves, is commonly practiced in livestock industry as a profitable breeding alternative, especially in dairy farming. The flow cytometric cell sorting is the only commercially available method for bovine sperm sexing. For validation of the sexing procedure several methods have been developed including sperm fluorescence in situ hybridisation techniques.

A significant proportion of mammalian fertilization is mediated through the proteomic composition of the sperm surface. These protein constituents can present as biomarkers to control and regulate breeding of agricultural animals. Previous studies have addressed the bovine sperm cell apical plasma membrane (PM) proteome with nitrogen cavitation enrichment.

Background: Previously we have reported on the development of a new mouse anti-titin monoclonal antibody, named MAb Titl 5 H1.1, using the synthetic peptide N-AVNKYGIGEPLESDSVVAK-C which corresponds to an amino acid sequence in the A-region of the titin molecule as immunogen. In the human skeletal muscles, MAb Titl 5 H1.

We report on the development of a mouse monoclonal antibody (named F10H2.B3) using the native cellular fragments of human fetal neural stem cells as immunogens. Molecular analysis has shown that the target antigen of F10H2.

We have studied the expression of CC-chemokine receptor 5 (CCR5) at the protein level in human fetal neural stem/progenitor and glioblastoma cells in differentiation, using immunocytochemistry, routine fluorescence microscopy and confocal laser microscopy analysis. Neural stem/progenitor cells were isolated from the brain of 18-21 weeks old fetuses aborted due to medical indications, and propagated in vitro as neurospheres. Glioblastoma cells were isolated from tumour biopsies and propagated in vitro as spheres according to the same methods as fetal neural cells.

The purpose of this study was to determine the CCR5-del32 allele frequency in type I (insulin-dependent) and type II (noninsulin-dependent) diabetes patients, and to test whether and how this mutation is associated with both types of diabetes. Thirty-eight type I diabetes and 111 type II diabetes patients' genotyping was performed by polymerase chain reaction assaying, and amplified products were digested with restriction enzyme EcoRI. The results were analyzed using statistical methods.
