Collection: Protein Sample Preparation

Protein Sample Preparation — contains solutions and supporting reagents for the early stage of protein analysis, including extraction buffers, denaturing agents such as urea and thiourea, and zwitterionic and anionic surfactants. This group functions to dissolve, denature, and stabilize proteins before further analysis.

Protein Sample Preparation is used by biochemistry and proteomics researchers to lyse bacterial and yeast cells and to dissolve membrane proteins that are difficult to extract with conventional buffers. Reagents such as urea and thiourea help denature proteins so they unfold completely before two-dimensional electrophoresis, while EDTA salts are added to chelate metal ions that can interfere with sample integrity.

Example products in this collection: TCI Y0021 E.coli / Yeast Protein Extraction Buffer, TCI B6279 Nervous Tissue Protein Extraction Buffer, TCI U0077 57-13-6 Urea [for Biochemical Research], TCI D1820 302-95-4 Sodium Deoxycholate [for Electrophoresis], TCI T3071 50996-85-5 Tris Dodecyl Sulfate [for Biochemical Research], TCI D3789 6381-92-6 Disodium Dihydrogen Ethylenediaminetetraacetate Dihydrate [for Biochemical Research], TCI T2835 62-56-6 Thiourea [for Biochemical Research], TCI D3860 14933-08-5 Dodecyldimethyl(3-sulfopropyl)ammonium Hydroxide Inner Salt [for Biochemical Research].

Pay attention to the purity grade suitable for biochemical use (research grade), and to the compatibility of surfactants with downstream analytical methods such as mass spectrometry or electrophoresis. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
