Protein precipitation is an optional step in sample preparation for 2-D electrophoresis. Precipitation, followed by resuspension in sample solution, is generally employed to selectively separate proteins in the sample from contaminating species such as salts, detergents, nucleic acids, lipids, etc., that would otherwise interfere with the 2-D ...

A step-by-step guide to successful chromatin immunoprecipitation (ChIP) assays oligoclonal (pools of monoclonals), and polyclonal antibodies all can work in ChIP. The key requirement is that the specific epitope of interest be exposed. One of the advantages of …

Co-immunoprecipitation (Co-IP) is a widely used technique to isolate target proteins and their binding partners from cell lysates. It involves incubating lysates with specific antibodies, extracting antibody/antigen complexes using protein A/G agarose beads, and analyzing the isolated proteins through Western blot.

Fractional precipitation is frequently used at laboratory scale to remove gross impurities from small sample volumes and occasionally used in small-scale commercial production. Precipitation techniques separate fractions by the principle of differential solubility.

2023年8月11日 · Today, we're diving into the world of protein precipitation, a crucial step in sample preparation for various analyses. This guide will provide you with a step-by-step walkthrough, ensuring you have a thorough understanding of the process.

In some cases, precipitation can be useful as a combined protein concentration and purification step. Precipitation techniques separate fractions by the principle of differential solubility. For example, because protein species differ in their degree of hydrophobicity, increased salt concentrations can enhance hydrophobic interactions between ...

2023年6月1日 · The present study describes an LC-MS/MS method by one-step precipitation for determination of cinacalcet in human plasma. The method was simple, rapid, economical and has been validated according to the recommendations of the Pharmacopoeia of the People’s Republic of China (Edition 2020) and guidelines of FDA. 2. Materials and methods. 2.1.

2023年5月23日 · A step-by-step guide to immunoprecipitation (IP), including lysate preparation, immunoprecipitation, and elution.

Here is the general step wise procedure for nanoprecipitation. 1. Dissolve your drug and polymer in a suitable organic solvent (Eg., Acetone, THF, ACN) 2. Prepare an aqueous surfactant solution...
