Project Update: Open Colorimeter Plus & Fluorescence Measurements
Update to the Open Colorimeter Plus hardware design including new excitation LEDs & testing different emission filters.
Lab Science
DNA Quantification with the UV Open Colorimeter
In this post we share some information on using the UV Open Colorimeter with a 255nm UV LED board for nucleic acid measurements.
Protein Quantification with the UV Open Colorimeter
In this tutorial we are using the new UV Open Colorimeter for A280 protein quantification measurements using a UV sensor and 270-280 nm UV LED
Background
Protein concentration is an extremely useful and routine measurement in science with a wide variety of applications in biochemistry, molecular biology, environmental and biomedical
Measuring proteins with the Bradford assay
Methods for measuring protein concentration using the Open Colorimeter and 595nm LED.
Measuring beer color with a 430nm colorimeter
Revisiting and sharing some of our earlier work developing a beer color test for home brewers.
Open Colorimeter Plus: Implementing the dual light sensor design
In this post we provide an update on the Open Colorimeter Plus design. Using different white light LED boards we measured baseline light intensity and the scattered light intensity from a single 100 NTU turbidity standard.
DNA Quantitation with the Open Colorimeter Plus
In this post we describe how to perform DNA Quantitation with a commercial dsDNA fluorescence kit and our new Open Colorimeter Plus.
