Protein kinase C activity in boar sperm

The Extraction and Purification of Boar Sperm Surface Protein

Immunological sperm sexing is one of the desirable choices to separate X and Y sperm. The basic concept of immunological technique is based on the different proteins on the surface of X and Y sperms. To investigate the sperm surface proteins, proteomic investigation using 2 dimensional gel (2D-gel) electrophoresis technique has been applied. The initial step, protein extraction is very importan...

Factors influencing boar sperm cryosurvival.

Optimal sperm cryopreservation is a prerequisite for the sustainable commercial application of frozen-thawed boar semen for AI. Three experiments were performed to identify factors influencing variability of postthaw sperm survival among 464 boar ejaculates. Sperm-rich ejaculate fractions were cryopre-served using a standard freezing-thawing procedure for 0.5-mL plastic straws and computer-cont...

The Effect of Cigarette Smoking on Human Sperm Creatine Kinase Activity: As An ATP Buffering System in Sperm

Concentrations of sperm, protein and a sperm membrane glycoprotein within boar epididymal luminal fluids.

Boar rete testis fluid and luminal contents from nine epididymal segments were collected for analysis. From proximal to distal, segments were designated A, B, C (caput), Da, Db, Ea (corpus) and Eb, Fa, Fb (cauda). Concentrations of sperm, protein and soluble sperm membrane glycoprotein S2P3 were lowest in the caput epididymidis (region A) and highest in the proximal corpus epididymidis (region ...

Partial purification of a boar sperm membrane protein inducing sperm agglutinating antibody.

For the development of immunological contraception, attention is being concentrated on the possibility of using a sperm membrane antigen. Boar sperm membrane was extracted with triton-X 100 and fractionated by Sephadex G-150 column chromatography. The glycosylated and nonglycosylated portions of protein peaks from the gel filtration were obtained by fractionating on concanavalin A-Sepharose and...
