Hi, so about 3 weeks or a month or so back I made a sodium chlorate cell running with a carbon anode and a stainless steel cathode. It was running at about 1.9A at the start of the cycle, I didn''t measure it at the end but the reaction was way slower, so I thought it would be alright to get it out of the process.

The product generally has 30 ppm sodium chloride and 5-10 ppm sodium chlorate. Diaphragm-cell catholyte contains 10-12% sodium hydroxide, 14% sodium chloride, 0.25%-0.3% sodium sulfate, and 100-500 ppm …
Background: Tyrosine sulfation is a post-translational modification found on many surface receptors and plays an important role in cell-cell and cell-matrix interactions. However, tyrosine sulfation of therapeutic antibodies has only been reported very recently. Because of potential potency and immunogenicity concerns, tyrosine sulfation needs to be controlled …
