Western Blotting Sample Preparation Optimization

The first step to obtaining a clear, accurate Western blot is sample preparation. The critical step of sample preparation, the choice of protein extraction method, is a crucial one which ultimately makes the difference between a blank blot and a beautiful one. Boster supplies a range of lysis buffers and specialized extraction kits; use this guide to pick the right one for your task and start getting better results.

Western Blotting Protein Quantification Optimization

One of the first issues to consider when conducting a total protein assay is the type of assay to use. A primary factor to consider in making your choice is the compatibility of the assay with the samples. The objective is to select an assay that requires the least manipulation or pre-treatment of the samples, and will give good results for your sample type.

Western Blotting Antibody Concentration Optimization

No single antibody or antigen concentration will work for every experiment. In order to obtain the most perfect Western blots, the antibody concentration needs to be optimized. The ideal antibody concentration is dependent on the concentration of antigen, the specificity and affinity of the antibody, and experimental conditions such as buffer composition. Use this guide to help optimize your antibody concentration and get better results:
