1344-E - Microplate Surface Compounds that effect Assays and are removed by Plasma Cleaning

Data from an experiment will be presented that compares three brands of microplates used to run a uniform maximum signal assay.


 


Results show that NH4 and small chain carbon compounds measured by ToF-SIMs analysis were reduced an average of 30% with one cleaning and 45% with 5 cleaning cycles.  


 


A similar analysis of the effect of surface ions, specifically Na+, Al+, K+, Ca+ and Zn+ were only slightly reduced by the same process but it was found that a pattern effect of all the ions correlated with statistically significant differences in cell growth rates.
