Other Notes

The pH values of all buffers are temperature- and concentration-dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.
Easily compare specifications for Trizma products with the Trizma specification table.

The visual cortex is organized into discrete domains characterized by their specific function, connectivity, chemoarchitecture, and cytoarchitecture. Gradients of transcription factors across the anteroposterior and mediolateral axes of the neocortex have previously been demonstrated to specify the main sensory regions.
