Isoelectric Focusing

Information on Isoelectric Focusing including what it is and how it is used. In order to ensure the high performance of analysis, isoelectric point (pI) standards are needed.

Fast determination of catechins and xanthines in tea beverages by micellar electrokinetic chromatography.

Matteo Bonoli et al.

Journal of agricultural and food chemistry, 51(5), 1141-1147 (2003-02-20)

Antioxidant properties and stimulating effects of green tea are related to its content of cathechins and xanthines; tea quality evaluation is based on organoleptic tests and on the presence of those components. In this work, by a MEKC method, eight

The linear ubiquitin assembly complex (LUBAC) is essential for NLRP3 inflammasome activation.

Mary A Rodgers et al.

The Journal of experimental medicine, 211(7), 1333-1347 (2014-06-25)

Linear ubiquitination is a newly discovered posttranslational modification that is currently restricted to a small number of known protein substrates. The linear ubiquitination assembly complex (LUBAC), consisting of HOIL-1L, HOIP, and Sharpin, has been reported to activate NF-κB-mediated transcription in

Protective efficacy of passive immunization with monoclonal antibodies in animal models of H5N1 highly pathogenic avian influenza virus infection.

Yasushi Itoh et al.

PLoS pathogens, 10(6), e1004192-e1004192 (2014-06-20)

Highly pathogenic avian influenza (HPAI) viruses of the H5N1 subtype often cause severe pneumonia and multiple organ failure in humans, with reported case fatality rates of more than 60%. To develop a clinical antibody therapy, we generated a human-mouse chimeric
