Absorbance assay at 280 nm. This method is just as convenient as for absorbance at 280 nm. It may be preferred if there is excessive contamination by nucleic acids, since nucleic acids absorb very little radiation at 205 nm. Setting the wavelength is a bit tricky since 205 nm is right on the shoulder of the protein peak. - [Read Absorbance Assay 205 nm]
This procedure describes a method for establishing short-term explant cultures of oesophageal mucosa. Adverse effects produced by exposure to radiation or test compounds can be detected as an inhibition of cell outgrowth. - [Read Human Oesophageal Culture Protocol]

The latest generation of Promega cell-based assays includes luminescent and fluorescent chemistries to measure markers of cell viability, cytotoxicity and apoptosis, as well as to perform reporter analysis. Using these tools researchers can investigate how cells respond to growth factors, cytokines, hormones, mitogens, radiation, effectors, compound libraries and other signaling molecules. The protocols provided are guidelines for multiplexing cell-based assays & are intended as starting points. - [Read Multiplexing Cell Viability Assays Protocols]

UV Absorbance 280 nm Protein Determination. Simple and quick method to accurately quantitate total protein in purified material or approximately quantitate total protein in crude lysates or partial purified material. Quantitation of the amount of protein in a solution is possible in a simple spectrometer. Absorption of radiation in the near UV by proteins depends on the Tyr and Trp content (and to a very small extent on the amount of Phe and disulfide bonds).
