WebBioimpedance Analysis. Bioimpedance analysis (BIA) is a method of estimating body fluid volumes by measuring the resistance to a high-frequency, low-amplitude alternating electric current (50 kHz at 500 to 800 mA). The amount of resistance measured ( R) is inversely proportional to the volume of electrolytic fluid in the body and to a lesser ...

WebToo high, may start identifying live cells as dead. Defines whether there is a cell present or not. Minimum Circularity. 0 to 0.60. 0 to 1.00. More irregular shaped dead cells will be excluded. Less irregular shaped dead cells will be excluded. Unwanted irregular shaped debris are being picked up. WebThey irreversibly conjugate to primary amine-containing proteins. Since there is a greater abundance of proteins inside the cell versus the cell surface, dead cells with a compromised membrane stain brighter than live cells with an intact membrane. Thus, they can be used to assess live vs. dead status of mammalian cells. jay white neil diamond schedule
