General description
Universal Food pathogen ID Membranes are substrate-carrying membranes used for rapid identification and differentiation of food pathogens through characteristic color reactions by placing on the agar surface post-incubation. The membranes contain chromogenic substrates such as ONPG, X-Gal, or X-Glu, and other substrates and indicators, which serve as the basis for microbe differentiation by color. The target organisms possess enzyme systems that metabolize the substrates in the membrane, leading to a change of color. The colors can be visually detected on the membrane. This indicates microbial enzymatic activity which serves to identify the genus and species. This economical, confirmatory and rapid identification method is suitable for microorganisms from various food, dairy, fish, and meat products.
Application
Universal Food pathogen ID Membrane is recommended for detection of food pathogens such as E. coli, E. coli O157:H7, Staphylococcus aureus, Salmonella, Bacillus, Listeria, and Shigella species, etc. from various food, dairy, fish, and meat products. They find their application in various sectors such as the water, food, and dairy industry.

Biological phase transitions form membrane-less organelles that generate distinct cellular environments. How molecules are partitioned between these compartments and the surrounding cellular space and the functional consequence of this localization is not well understood. Here, we report the localization of

Sustained changes in mood or action require persistent changes in neural activity, but it has been difficult to identify the neural circuit mechanisms that underlie persistent activity and contribute to long-lasting changes in behavior. Here, we show that a subset

Apical-basal polarity is a common trait that underlies epithelial function. Although the asymmetric distribution of cortical polarity proteins works in a functioning equilibrium, it also retains plasticity to accommodate cell division, during which the basolateral determinant Lgl is released from
