产品名称：ProStain Protein Quantification Kit
Contents & Storage
Determining the protein concentration of cell extracts is an essential step in many modern cell biology procedures, such as Western blot and ELISA. Not surprisingly, there are numerous photometric and fluorescent methods for quantifying cell extract protein levels. Photometric methods have traditionally been based either on intrinsic absorbance at 280 nm or on reagent-based methods such as the Bradford and Lowry assays. However, these classical approaches tend to be time consuming, have limited sensitivity and may be influenced by the presence of contaminating substances. Fluorescent-based detection methods, while generally more sensitive, have also tended to suffer from limitations, such as the requirement for toxic co-factors, high rates of hydrolysis or unsuitable spectral properties. The ProStain Kit offers significant improvements in sensitivity, assay robustness and convenience when compared with existing methods.
Each ProStain Kit supplies sufficient reagents for 1000 reactions. All reagents can be stored at 4°C and are guaranteed stable for 6 months when stored properly.
