Application Notes

Determination of Lactate Concentration Using Photopette® Cell

This application note provides an easy and fast enzymatic assay to quantify lactate in biological samples such as serum, plasma, urine, cell culture/fermentation media or in food & beverage products using Photopette®.

Determination of Ethanol In Alcoholic Beverages Using Photopette® Cell

The objective of this application note is to demonstrate how Photopette® Cell can be used to quantify the amount of ethanol in beverages on the example of wine.

Hela Cell Counting by Optical Density Measurements with Photopette®

This application note is to demonstrate how Photopette® can be used for measurement of cell number by optical density. Advantageously, Photopette® enables cell number measurements directly in the cell culture hood. This application note demonstrated cell number measurements of HeLa cell lines, how to prepare a calibration curve and to determine the biomass in the cell suspension. Furthermore, it acts as a handy guide to get you started with Photopette®, and outlines application-specific parameters for reference.

Measuring Cell-Viability by Resazurin (Alamarblue) Assay using Photopette® Cell

This application note is to demonstrate how Photopette Cell can be used to measure cell-viability of eukaryotic cells using a Resazurin Assay. Furthermore, it acts as a handy guide to get you started with Photopette Cell, and outlines application-specific parameters for reference.
