Differential Refractometer for Precise Protein Analysis

May 24 2021 The new HK Series Differential Refractometer from Testa Analytical Solutions eK sets a benchmark for precise determination of specific refractive index increment (dn/dc) - an important parameter for polymer and protein molecular weight determination using light scattering techniques. The specific refractive index increment (dn/dc) is one of the most underestimated parameters in material science. The assumption that using the approximate values for many polymers and proteins in published literature will not have a huge impact on molecular weight values determined by light scattering experiments, with or without GPC/SEC separation is incorrect. Because dn/dc is a squared term in the Debye Constant of the Zimm equation, any error in determining dn/dc will result in introducing considerable errors into molecular weight determination. In addition to this, precise determination of dn/dc within a GPC/SEC application, is extremely useful in order to calculat

New Products

Cytosections for Antibody Screening AMS Biotechnology (AMSBIO) has launched a comprehensive range of cytosections that offer a verified, reproducible, and renewable source of positive/negative controls where the expression of the target biomarker is confirmed for accuracy and specificity by an immunoassay. Researchers, antibody and assay developers, and immunohistochemistry (IHC) labs often have difficulty finding a reliable and verified source of positive/negative controls for their IHC experiments. AMSBIO s new cytosections range consists of high-quality FFPE sections of cell pellets of overexpressing targeted biomarkers. The expression of target biomarkers in these cytosections is carefully verified for accuracy and specificity using Western blot. Positive controls (cells transfected with the target protein) and negative controls (mock transfected cells) are available for genome-wide human and mouse genome targets. In addition to its standard range, AMSBIO also offers a custom cy
