Positive Beta Decay – Positron Decay.In positron decay, a proton-rich nucleus emits a positron (positrons are antiparticles of electrons and have the same mass as electrons but positive electric charge), thereby reducing the nuclear charge by one unit. In this case, the ...

Unit definition: One unit is defined as the amount of enzyme that hydrolyzes 1 μmol of substrate (ONPG) per min under the assay conditions. c. Substrate specificities E. coli βGal shows a wide range of activities depending on the property of the leaving group (also called aglycon) (20)...
Gram-positive bacteria have a wall approximately 50 nm thick containing teichoic acid and peptidoglycan, made up of repeating N-acetyl-glucosamine and N-acetyl-muramic acid. The wall of Gram-negative bacteria is separated from the cell membrane by the periplasmic space, is much thinner, contains...

Despite joint internalization of all IL-2R subunits, in the later steps the α chain was shown to be transported independently of other chains, being directed to transferrin-positive structures, most likely early recycling endosomes, while never reaching lysosomes [117]. This is consistent with a...
