• • Bradford Protein Content Determination Experiment Report

  Objective: The aim of this experiment is to quantify protein concentration via the Bradford assay. Principle: The Bradford assay is based on the binding of Coomassie Brilliant Blue G-250 to proteins, forming a stable blue complex. The absorbance of this complex peaks at 595 nm when in an acidic environment, enabling the determination of protein concentration.

• • Numerical Y-Coordinate of Circular Dichroism Spectrum

  In circular dichroism (CD) spectroscopy, the vertical axis represents either the absorbance or transmittance of light, determined by the ratio of the intensity of light passing through the sample to that passing through a reference material. This ratio is commonly referred to as "transmittance," denoted by "T," or "absorbance," denoted by "A," with absorbance often being the logarithmic form of the transmittance ratio. Circular dichroism is an analytical technique that assesses the chemical composition a...

• • Host Residual DNA Detection

  In the fields of biological research and bioproduct manufacturing, particularly during biopharmaceutical production, the detection of host residual DNA represents an indispensable quality control measure. Residual DNA from host organisms may persist through production processes, potentially compromising the quality, safety, and therapeutic efficacy of the final product.
