„ElphoGels SAR“ are designed for Ready-To-Use horizontal SAR-electrophoresis of EPO-samples for anti-doping controls in blood and urine .
SAR-electrphoresis is a special mol-weight delivering electrophoresis using N-Laurylsarcosine sodium salt (SAR, Sarcosyl) as tensid instead of Sodiumdodecyl-sulfat (SDS) .
In contrary to SDS as tensid, the Sarcosyl will not complex and transport the Polyethyleneglycol (PEG) molecules and -chains.
With Sarcosyl as tensid, Mircera (Cera) shows a normal band whereas using SDS causes a broad backward striking .
After electrophoresis the SAR-gel is contact-blotted ,  in the BEO contactblotter; Dyeagnostics
Visualization: chemoluminsescent antibody reaction, the result is scanned .
Alternative methods: EPOetins on DryGels IEF
