This procedure may be used for all Alcohol Oxidase products. The continuous spectrophotometric rate determination (A405, Light path = 1 cm) is based on the following reactions.
In recent years, array-based Comparative Genomic Hybridization (aCGH) has been refined to determine chromosomal changes at progressively higher resolutions. This evolving technology is, however, somewhat hampered by the large DNA input requirement—a minimum of 150,000 copies of a human genome
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer
Immunohistochemistry (IHC) is used to characterize intracellular proteins or various cell surfaces in all tissues. Individual markers or more often panels of various marker proteins can be used to characterize various tumor subtypes, confirm tissue of origin, distinguish metastatic from
The effects of the mononuclear cell separation method described by Bøyum procedure are noted below, since research situations may arise in which they are significant.
Use the calculator to determine the boiling point or pressure of solvents based on the Antoine Equation and see solvent attributes. View a list of products based on the solvent CAS number.
Graphene is a unique two-dimensional (2D) structure of monolayer
carbon atoms packed into a dense honeycomb crystal that has attracted
great interest due to its diverse and fascinating properties.
Optimizing the synthesis of high-quality 2D MXene flakes for 3D ink printing is essential to such technological developments as printable and flexible electronics.
The following procedure has been evaluated with Ficoll-Paque PLUS and is recommended for separation of normal blood samples for maximum reproducibility.
Colorectal cancer is the third most common cancer in both men and women. An estimated 136,000 cases of colorectal cancer are expected to occur in 2016.
Advanced technologies for energy conversion and storage are widely sought after for their potential to improve consumer and electronic device performance as well as for the prospect of reducing the societal and environmental impact of energy generation.
For several decades, the need for an environmentally sustainable and commercially viable source of energy has driven extensive research aimed at achieving high efficiency power generation systems that can be manufactured at low cost.
Immunohistochemistry (IHC) techniques and applications have greatly improved, dermatopathology is still largely based on H&E stained slides.This paper outlines ways in which IHC antibodies can be utilized for dermatopathology.
