WebbThe Sperm Chromatin Structure Assay (SCSA) serves as a tool for measuring clinically important properties of sperm nuclear chromatin integrity. The assay utilizes the metachromatic features of Acridine Orange (AO), a DNA probe, and the principles of flow cytometry (FCM). WebbThe sperm chromatin structure assay (SCSA) was introduced by as a method to determine the susceptibility of sperm DNA to denaturation and how those results related to fertility. This initial study used human sperm and was followed by studies in bulls and boars . Webb1 juni 2016 · The Sperm Chromatin Structure Assay (SCSA ®) was named as such since it measures both sDF and abnormal chromatin structure. The major use of the SCSA test has been to determine the percent of sperm with fragmented DNA. proxy card template

Webb摘要： Sperm chromatin integrity is vital for successful pregnancy and transmission of genetic material to the offspring. We evaluated chromatin integrity in sperm from 60 infertile men and 7 fertile donors comparing the sperm chromatin structure assay (SCSA), TdT-mediated-dUTP nick end labeling (TUNEL), the sperm chromatin dispersion (SCD) … Webb临床诊疗知识库; 中医药知识库; 检索机构; 作者

Sperm Chromatin Structure Assay (SCSA) is a diagnostic approach that detects sperm abnormality with a large extent of DNA fragmentation. First described by Evenson in 1980, the assay is a flow cytometric test that detects the vulnerability of sperm DNA to acid-induced denaturation DNA in situ. SCSA measures sperm DNA fragmentation attributed to intrinsic and extrinsic factors and reports the degree of fragmentation in terms of DNA Fragmentation Index (DFI). The use of SCSA expan… Webb1 jan. 2012 · The SCSA ® is considered to be the most technician friendly, time- and cost-efficient, precise and repeatable DNA fragmentation assay, with the most data and the only fragmentation assay with an accepted clinical threshold for placing a …
