Peptides are used to prepare antibodies, map antibody epitopes and enzyme binding sites and to engineer enzymes, drugs and vaccines.
Peptides are chemically synthesized by the condensation reaction of the carboxyl group of one amino acid to the amino group of another. Protecting group strategies are necessary to prevent undesirable side reactions with the various amino acid side chains. Automated peptide synthesizers use UV absorbance measurements to monitor and control the process.
UV Absorbance signals are weak. In order to maintain an adequate SNR and, more importantly, an excellent linearity, it is essential to select an optical spectrometer platform with very low stray light. Concave gratings, by their design, correction of the aberrations and simplicity of use deliver the required ultimate performance.
tec5USA CGS and MCS Series of spectrometers are the ideal candidates for optimized absorbance measurements.
FAQ
Typical applications include white light interference for thin film analysis, UV absorption of proteins for quantitative analysis, colorimetry, impurity detection in water, cleaning validation for API manufacturing, polymerization inhibitor monitoring, electroplating bath monitoring....
The spectroscopic methodology is determined by which parameters are important to monitor during a process. For example, if you want to monitor protein concentration in a bioreactor, in which the biosynthesis takes place in an aqueous medium, then you likely would want to use Raman spectroscopy for the application, as water does not contribute to the Raman signal. Alternatively, if moisture content is important, water has very strong absorption in the NIR due to several vibrational and combination modes that can be monitored; water is transparent in the UV and visible spectral region. Understanding which chemical is important as there could be various factors that influence the choice of methodology....
