Selleck Chemical LLC Tween 80 | 99% | 9005-65-6 | 100mL
Tween 80 is a polysorbate surfactant used for selective protein extraction and the isolation of nuclei from mammalian cell lines. Tween 80 has been used in drug vehicle solutions for specific injections in mice and rats. It has been used for the determination of esterase activity in bacterial cells..
Boston Bioproducts Inc Tris Buffered Saline-Tween, TBST (10X, with 0.5% Tween-20, pH 7.4) - 1L
10X Tris Buffered Saline - Tween (TBST) is a buffer-surfactant solution supporting a stable pH range between 7.4 and 8.0. When combined in a variable ratio, TBST is an effective wash buffer in Western blotting, in situ hybridization procedures, and immunohistochemistry staining, as it minimizes non specific binding of the materials without disrupting antigen-antibody binding. TBST is also used as an antibody diluent in immunoassays, and supports an array of molecular biology techniques.

Gold Biotechnology Inc n-Dodecyl-B-D-maltoside (DDM) 10 g
n-Dodecyl-B-D-Maltoside, or DDM, is a maltoside based non-ionic detergent with a hydrophilic maltose head and a hydrophobic long chain alkyl tail. It is considered a gentle detergent that is more efficient than other detergents, such as CHAPS or NP-40. It has a comparatively low critical micelle concentration (CMC) of 0.17mM compared to the other maltoside based detergents.
Boston Bioproducts Inc Phosphate Buffered Saline-Tween, PBST (20X, with 1% Tween-20, pH 7.4) - 1L
20X Phosphate Buffered Saline with Tween-20 (PBST) is a specialized variant of PBS, supplemented with Tween-20, a non-ionic surfactant. Tween-20 minimizes the non-specific binding and background noise, resuting in enhanced signal to noise ratio. PBST is often used in immunoassays such as ELISA and Western Blotting, where it serves as a washing and blocking buffer. With a stable buffering pH range between 7.0 and 7.4, PBST maintains ionic strength and protein solubility for biological assays.

Waters Corp RapiGest SF, 3 mg, 1/pk
RapiGest SF, is a patented anionic surfactant that drastically improves in-solution protein digestion in terms of speed and peptide recovery. It is especially valuable in protein sample preparation for mass spectrometry (MS) analysis by avoiding high background noise often seen from other common surfactants.
RapiGest SF is available in a variety of formats. This part contains one, 3 mg vial. Add RapiGest SF to your proteolytic digestion, (using trypsin, PNGase F or other enzymes) to enhance digestion speed and increase peptide recovery.
