| Bioactivity | HEPES, a nonvolatile zwitterionic chemical buffering agent, is broadly applied in cell culture. HEPES is effective at pH 6.8 to 8.2. HEPES is also a potent inducer of lysosome biogenesis[1][2][3]. | ||||||||||||
| Invitro | HEPES maintains superhydrophilicity of titanium for at least 3 months and resulted in a continuous retention of bioactivity and osteoconductivity[1].HEPES drives lysosome biogenesis, affects MiT/TFE cytoplasmic-nuclear distribution, disrupts global cellular transcriptional profiles, resulting the activation of a MiT/TFE-dependent lysosomal-autophagic gene network in cultured RAW264.7 cells[3]. | ||||||||||||
