How Does A Lateral Circulation Test Work?
Sodium dodecyl sulfate was used as a candidate for ionic cleaning agents, Triton X-100 and also Tween-20 were used as examples of nonionic detergents, as well as urea was added as a chaotropic detergent. Our outcome showed that ionic cleaning agent SDS (1%) enhanced the signal strength as much as 75%. SDS had the least renovation result in the presence of 10 mM Tris pH 7.4. Simultaneous existence of BSA as well as SDS could increase the signal up to 97%. As an example, the signal strength of the examination with 1X PBS in the existence of 1% SDS and 4% BSA as running barrier was almost twice of the signal strength of the band when 1X PBS was made use of exclusively. Addition of nonionic detergents, Triton X-100 and Tween-20, reduced the signal strength approximately 90%. The even worse result was for 4X SSC barrier, and the least severe result was for 10 mM Tris pH 7.4.
