What reagent grades, purity labels and specifications mean: ACS/AR, HPLC, electronic grade and tag-grade proteins, in 190+ guides from Aladdin Scientific.
Labels such as “purum,” “puriss.,” and “p.a.” are frequently seen on chemical reagent labels and in product catalogs. Purum is commonly translated as “pure” or “pure grade,” but it is not a standardized grade that is uniformly applied across suppliers or associated with a ...
In tissue engineering research, materials are used not only as reaction raw materials but may also come into direct contact with cells, encapsulate cells, form three-dimensional scaffolds, or participate in the construction of bioinks and injectable hydrogels. Therefore, the evaluation of these ...
Purity is an important indicator in reagent specifications used to characterize the target component, target element, active component, or specific quality attribute. In actual product labeling, purity does not always equal the mass percentage of a single compound. Its meaning may be jointly ...
Electronic-grade reagents are mainly used in semiconductors, display panels, photovoltaics, light-emitting diodes, printed circuit boards, electronic components, precision cleaning, and high-end trace analysis. Their main difference from ordinary laboratory reagents is not simply higher assay or ...
The AVI-tag grade is a product quality and technical standard level established around the AviTag and the biotin–streptavidin system. This grade emphasizes achieving highly efficient, quantitative, and site-specific biotinylation of target proteins in advanced applications such as protein ...
T7 tag grade is a product quality and technical standard system built around the T7 short-peptide epitope tag and specific anti-T7 antibody–based detection. This grade emphasizes, in applications such as recombinant protein expression verification, qualitative or semi-quantitative detection, ...
The c-Myc tag grade is a product quality and technical standard established around the c-Myc epitope tag and the anti–c-Myc immunorecognition system. This grade emphasizes achieving sensitive, specific, and quantitative immunodetection and spatial localization of target proteins in molecular ...
Fc tag grade is a product quality and technical standard level established around Fc (antibody constant region) fusion tags, Fc affinity ligands such as Protein A/G, and Fc functional assay systems. This grade emphasizes systematic control of key factors in applications including recombinant ...
FLAG tag grade is a product quality and technical standard defined around the FLAG short peptide epitope tag, anti-FLAG antibodies/affinity media, and the corresponding immunodetection and immunoaffinity purification systems. This grade emphasizes systematic control of key factors such as FLAG ...
