endo-BCN-PEG8-amine is a PEG linker featuring a BCN and a primary amine. The BCN group is a click chemistry handle which quickly reacts with azides while the primary amine can be used to form amides with carboxylic acids in the presence of coupling reagents such as HATU or EDC.

Cell Culture Flask T25

Cell Culture Flask surface is very smooth based on precise molding technology and it gives clear view when examined with microscope.

Volume: 25mL75mL175mL225mL

PRODUCT FEATURES

• The product is made of medical grade USP CLASS VI polymer polystyrene
• The product is made under a 100,00- class dust-free manufacturing site
• Two kinds of product line up are providing.

For adherent cell culture: Initial adherence and proliferative property of cells via hydrophilic surface treatment.

For suspension cell culture: The surface is resistant to cell adherence, which minimizes damage or loss of cell.

• Large mouthed design makes easy operation of pipet or cell scraper. The surface of flask is uniform and smooth, hence the clear view can be obtained when microscopic observation.
• The hydrophobic filter cap can prevent invasion of fungi and bacteria without water absorb.
• Gamma radiation sterilization
• Non-Pyrogenic, DNase/Rnase free.

Description

Tyrosinase Inhibitor Screening Kit (Colorimetric) provides a rapid, simple, sensitive, and reliable test suitable for high-throughput screening of tyrosinase inhibitors. Tyrosinase catalyzes the oxidation of tyrosine, producing a chromophore that can be detected at OD = 510 nm. In the presence of kojic Acid, a reversible inhibitor of tyrosinase, the rate of oxidation of the substrate is decreased.

Tyrosinase or polyphenol oxidase is an oxidoreductase that participates in the biosynthesis of melanin, a ubiquitous biological pigment found in hair, eyes, skin, etc. Inhibition of tyrosinase has been a long-time target in the skin health research, cosmetics and agricultural industries because of its role in browning reactions in skin pigmentation and during fruit harvesting and handling.

For rapid, sensitive and accurate screening of potential Tyrosinase inhibitors

TCO-PEG24-DBCO is a monodisperse, long PEG linker featuring a trans-cyclooctene and a DBCO group. DBCO easily reacts with azides through click chemistry, while the TCO group readily reacts with tetrazine-containing compounds.

The Total Dietary Fiber Assay Kit for the analysis of Total, Soluble and Insoluble Dietary Fiber according to AOAC and AACC approved methods.

View Dietary Fiber Measurement Guide – Which Method for which sample?

Dietary fiber can generally be described as the carbohydrate content of food that is not digested in the human small intestine. It passes into the large intestine where it is partially or fully fermented. These characteristics of dietary fiber are associated with its numerous well documented health benefits.

Dietary Fiber is a mixture of complex organic substances, including hydrophilic compounds, such as soluble and insoluble polysaccharides and non-digestable oligosaccharides, as well as a range of non-swellable, more or less hydrophobic, compounds such as cutins, suberins and lignins. The procedures for the determination and analysis of total dietary fiber as outlined in our assay protocol are based on the methods of Lee et al.¹ and Prosky et al.^2,3 (AOAC 991.43, AOAC 985.29, AACC 32-07.01 and AACC 32-05.01). However, the enzymes in the Megazyme Total Dietary Fiber Kit can also be used in other dietary fiber analytical methods such as AACC Method 32-21.01 and AACC Method 32-06.01.

See General Referee Reports: Journal of AOAC INTERNATIONAL, Vol. 81, No. 1, 1998. 

Two separate methods are described in the associated assay protocol:

METHOD 1: DETERMINATION OF TOTAL, SOLUBLE AND INSOLUBLE DIETARY FIBER
Based on AOAC Method 991.43 “Total, Soluble, and Insoluble Dietary Fiber in Foods” (First Action 1991) and AACC Method 32-07.01 “Determination of Soluble, Insoluble, and Total Dietary Fiber in Foods and Food Products” (Final Approval 10-16-91).

METHOD 2: DETERMINATION OF TOTAL DIETARY FIBER
Based on AACC method 32-05.01 and AOAC Method 985.29.

Note that a letter of endorsement from the original method developer, Dr. Leon Prosky, is included in the Documents Tab.
