Protein Quantitation in Microvolumes: New video of Colibri Here we show protein concentration determination in microvolumes using the A280 method. First we establish blank (buffer in which the protein is solved), then protein sample measurement takes place. Colibri automatically calculates the concentration of purified protein by using the A280 absorbance value and extinction coefficient. watch it here...
Automation of the Invitron Intact Proinsulin ELISA with Crocodile In this new application note we describe a convenient and easy to use method for automation of the intact Proinsulin ELISA assay from Invitron with Crocodile ELISA miniWorkstation. Precision and accuracy of results produced by the Crocodile were equivalent or better than an assay run manually with less hands-on time! download here...

How to determine DNA concentrations: New video of Colibri Learn how easy to use Colibri microvolume spectrometer for nucleic acid (dsDNA) quantitation. Simply turn on the instrument, pipet a drop of sample, obtain result and wipe off the sample!
In this new application note we describe a ssDNA oligonucleotide measurement series with Colibri microvolume spectrometer. Together with Karlsruhe Institute of Technology, Germany we can show excellent linearity and sensitivity down to 1ng/µL ssDNA.
