Accurately Quantifying Highly Concentrated Protein Solutions

The Lunatic, detailed in the following note, offers the ability to precisely quantify highly concentrated protein samples. Unchained Labs describes the caveats associated with the use of spectrophotometry on turbid samples, and how the Lunatic can overcome these. Tests of multiple IgG samples show a high level of precision and accuracy can be achieved with the Lunatic, whilst comparative spectrophotometry data demonstrates inter-instrumental variation, resulting in lower overall accuracy.
