Application

MES is a biological buffer often referred to as a “Good′s” buffer. The pKa of MES is 5.96 which makes MES an ideal candidate for medias and protein based buffer formulations to maintain a stable environment in solution. MES is considered to be non-toxic to culture cell lines, highly water soluble and provides high-solution clarity.

MES is used in cell culture media, biopharmaceutical buffer formulations (both upstream and downstream), and diagnostic reagents. MES based buffers are used in purification bioprocesses of antibodies, peptides, proteins, blood components and growth factors.

Oral delivery of antigens is patient-friendly and efficient way of treating intestinal infections. However, the efficacy of oral vaccines is limited by degradation in the gastrointestinal (GI) tract and poor absorption by enterocytes and antigen-presenting cells (APC). Here we report...

The stereoselective transport of methotrexate (L-amethopterin, L-MTX) and its enantiomer (D-amethopterin, D-MTX) by the rat proton-coupled folate transporter (rPCFT) were examined using rPCFT-expressing HEK293 cells. The initial rate of uptake of [3H]-L-MTX by the rPCFT followed Michaelis-Menten kinetics, with a...
