Liquid-liquid phase separation (LLPS) of a monoclonal antibody solution was investigated at low ionic strength in the presence of oligovalent anions, such as citrate, trimellitate, pyromellitate and mellitate. Phase separation was observed at the isoelectric point of the antibody at

A generalized, weighted, nonlinear least squares procedure is developed, based on pH titration data, for the refinement of octanol-water partition coefficients (log P) and ionization constants (pKa) of multiprotic substances. Ion-pair partition reactions, self-association reactions forming oligomers, and formations of

We studied the conjugates formed between hemoglobin and sulfated or unsulfated oxidized dextran. It appears that the presence of sulfated groups favors imino bond formation between the protein and the polymer, as the average molecular size of the conjugates is

Heating of the solid ammonium salts obtained from treatment of mellitic acid with 3 equiv of a primary amine yields trisubstituted mellitic triimides via dehydration and imide ring closure. This surprisingly simple synthetic approach is amenable to incorporation of alkyl

The (p)ppGpp-mediated stringent response is a bacterial stress response implicated in virulence and antibiotic tolerance. Both synthesis and degradation of the (p)ppGpp alarmone nucleotide are mediated by RelA-SpoT Homolog (RSH) enzymes which can be broadly divided in two classes: single-domain
