Universal buffers for use in biochemistry and biophysical experiments

open access: yesAIMS Biophysics, 2015
The use of buffers that mimic biological solutions is a foundation of biochemical and biophysical studies. However, buffering agents have both specific and nonspecific interactions with proteins.

Enzyme Immunoassay and Enzyme-Linked Immunosorbent Assay [PDF]

open access: yesJournal of Investigative Dermatology, 2013
inTrOducTiOn Enzyme immunoassay (EIA) and enzyme-linked immunosorbent assay (ELISA) are both widely used as diagnostic tools in medicine and as quality control measures in various industries; they are also used as analytical tools in biomedical research for the detection and quantification of specific antigens or antibodies in a given sample. These two

Simultaneous isolation of mRNA and native protein from minute samples of cells

open access: yesBioTechniques, 2014
Precious biological samples often lack a sufficient number of cells for multiple procedures, such as extraction of mRNA while maintaining protein in a non-denatured state suitable for subsequent characterization.
