Percoll discontinuous density gradient centrifugation method for the fractionation of the subpopulations of Mycobacterium smegmatis and Mycobacterium tuberculosis from in vitro cultures [PDF]

open access: yesMethodsX, 2023
Bacterial populations in the in vitro laboratory cultures, environment, and patients contain metabolically different subpopulations that respond differently to stress agents, including antibiotics, and emerge as stress tolerant or resistant strains.

Sperm selection of cryopreserved milt of catfish (Rhamdia quelen) by density gradient centrifugation with AllGrad® 90% [PDF]

open access: yesMethodsX, 2021
Density gradient centrifugation is a technique used to wash or separate samples of cryopreserved milt, mainly in humans and bovines allowing, for example, reducing the concentration of cryoprotectants or choosing the best portion of sperm.

Swim‐up method is superior to density gradient centrifugation for preserving sperm DNA integrity during sperm processing [PDF]

open access: yesReproductive Medicine and Biology
Purpose This study aimed to evaluate the effects of swim‐up and density gradient centrifugation methods on sperm DNA fragmentation. Methods Nineteen normozoospermic patient samples with ≥100 × 106 motile sperms were included in this study.

Comparison of Sperm Telomere Length between Two Sperm Selection Procedures: Density Gradient Centrifugation and Zeta Potential [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2020
Background Telomeres are particular sequences of DNA located at the end of the eukaryotic chromosomes that are essential for genome integrity. Telomere length in spermatozoa differs among males, as well as spermatozoa.

The influence of Percoll® density gradient centrifugation before cryopreservation on the quality of frozen wisent (Bison bonasus) epididymal spermatozoa [PDF]

open access: yesBMC Veterinary Research, 2022
Background The wisent (Bison bonasus) is a species that has undergone a population bottleneck. Homozygosity is prevalent within the population and may have a negative impact on semen quality in wisent bulls.
