Density gradient - Wikipedia, the free encyclopedia
Density gradient is a variation in density over an area. The term is used in the natural sciences to describe varying density of matter, but can apply to any quantity whose density can be measured. I...

Sucrose density gradient centrifugation and cross-flow filtration methods have been developed and standardised for the safe and reproducible production of inactivated arbovirus antigens which are appropriate for use in diagnostic serological applications.

Sun et al., 1997 ). The group of Evenson has shown that the sperm preparation techniques, density gradient centrifugation and glass wool filtration, can enrich sperm chromatin integrity when spermatozoa are assessed using the sperm chromatin structure assay (SCSA) (Larson et al., 1999 ). The SCSA measures the...

The ability of double-layered density gradient centrifugation (DGC) or glass wool filtration (GWF) of semen to remove spermatozoa with damaged chromatin structure was assessed by the flow cytometric sperm chromatin structure assay (SCSA), which measures the susceptibility to sperm nuclear denaturation in situ.

I have included the other methods as well because they are all very similar, and every now and then I see a fertility clinic offering a vaguely described method for gender selection, which is probably a density gradient centrifugation or modified sperm swim-up.
