N n n n tetramethyl ethylenediamine temed

Manufactured by Fujifilm
Sourced in Japan

N,N,N′,N′-tetramethyl-ethylenediamine (TEMED) is a chemical compound used as a catalyst in various laboratory applications, particularly in the preparation of polyacrylamide gels for electrophoresis. It is a clear, colorless liquid with a characteristic amine-like odor. TEMED functions by accelerating the polymerization of acrylamide and bis-acrylamide, which are the main components of polyacrylamide gels. The primary role of TEMED is to enhance the speed and efficiency of the gel formation process.

Chitosan (Chitosan LL, deacetylation: 80%, weight average molecular weight: 50–100 kDa) was purchased from Yaizu Suisankagaku Industry (Shizuoka, Japan). Lactobionic acid, N,N,N′,N′-Tetramethylethylenediamine (TEMED), and SPS were purchased from Wako (Tokyo, Japan). Ru(bpy)3·Cl2·6H2O, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC·HCl), and 3-(4-hydroxyphenyl) propionic acid (HPP) were purchased from Sigma-Aldrich (St. Louis, MO, United States of America (USA)), Peptide Institute (Osaka, Japan), and Tokyo Chemical Industry (Tokyo, Japan), respectively. Yatalase, with complex lytic activities of fungal cell, mainly consisting of chitinase and chitobiase activities, from Corynebacterium sp. OZ-21, was obtained from Takara Bio (Shiga, Japan). Escherichia coli OP50 was cultured in LB medium containing 0.5%(w/v) NaCl, 1%(w/v) bacto tryptone (Becton Dickinson and Company, Flanklin Lakes, NJ, USA) and bacto yeast extract (Becton Dickinson and Company). For culturing E. coli on an agar plate, LB medium containing 1.5%(w/v) agar was used. Staphylococcus aureus was extracted from facial skin as described in the literature [25 (link)] and cultured in BHI medium containing 3.5%(w/v) brain heart infusion (Nissui Pharmaceutical Co., Tokyo, Japan). For culturing S. aureus on an agar plate, BHI medium containing 1.5%(w/v) agar was used.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
