Bull Fertility and Its Relation with Density Gradient Selected Sperm

Background sperm selection is generally used to describe methods for separation of spermatozoa for in-vitro-assisted reproduction. Few studies reported relation in vivo fertility and semen parameters after selection of fertile spermatozoa; hence, our research attempt to assess different semen parameters after post-thaw (PT) or after selecting sperm sample (SSp), using density gradient separatio...

Motility and recovery of alpaca (Vicugna pacos) spermatozoa after centrifugation in a density gradient solution

Background: One of the factors limiting successful processing of alpaca (Vicugna pacos) semen is the viscosity of seminal plasma. The viscous nature of the collected ejaculate has hindered sperm cryopreservation as well as artificial insemination (AI) under field conditions. Aims: The objective of this investigation was to evaluate recovery, motility, ...

Sedimentation Equilibrium in a Density Gradient

Sedimentation equilibrium in a density gradient has recently been developed into a reliable method for the determination of molecular weights of homogeneous DNA samples. The procedure and calibrations required for this method are outlined in this paper. In 1957, Meselson, Stahl and Vinograd' introduced a remarkable analytical technique for studying the properties of DNA and viruses. Sedimentati...
