1. : a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates. 2.
Sperm DNA Fragmentation Test. The genetic integrity of the sperm is crucial for successful fertilization and normal embryo development. Sperm DNA fragmentation is a term used to denote when the genetic material within the sperm is abnormal, which in turn may lead to male subfertility and IVF failure.s a second generation sperm DNA test. It detects the sperm with DNA damage and also tells how much DNA damage each sperm have. A SpermComet test result of 45% means that there is an average of 45% damage in each sperm that was assessed.
DNA was size selected according to the Select-a-Size DNA Clean and Concentrator protocol and the results were analyzed by Bioanalyzer. 700 ng of sonicated salmon sperm DNA was used as a standard input to evaluate size selection efficiency and cutoff.elect-a-Size DNA Clean & Concentratorâ¢. Quick and easy 7 minute spin-column procedure to select for â¥300 bp, â¥200 bp, â¥150 bp, â¥100 bp, â¥50 bp DNA fragments or perform a double size selection. Clean and concentrate DNA from enzymatic reactions and library preparations in as little as 10 Âµl of nuclease free water.
