A titer is a measure of the concentration of a substance in a solution, typically referring to the concentration of antibodies or viruses in a biological sample. In the world of scientific research ...

This is a web application for calculating the most optimal cell concentrations for ELISA performance as well as analysis of absorbance readings.

Specific activity refers to the amount of enzyme activity per milligram of total protein in a sample. It measures the enzyme’s purity and can be helpful in comparing the quality of various enzyme ...

Dilute the dye to 0.2 g/L (Ci) with deionised water. Use the spectrophotometer to determine the maximum absorption wavelength and develop a “concentration-absorbance” curve using that value. Establish ...

An ELISA test should always be performed in replicates (duplicates or triplicates) so as to achieve enough number of samples to calculate the standard deviation and ...

Abstract: This research aims to study about developing and demonstrating the low-cost and portable light absorbance measurement device for using and learning in analytical experiments. The ...
