General description
Sodium phosphate dibasic heptahydrate is a hydrated form of disodium phosphate (DSP) or disodium hydrogen orthophosphate. DSP is widely used as a pH regulator and saline laxative.
Application
A mixture of sodium phosphate dibasic heptahydrate, potassium phosphate monobasic, and NaCl in deionized water is used for the preparation of phosphate-buffered saline (PBS, pH 7.4). PBS is used as a buffer solution in biological research to keep the pH constant.

Antitumoral immunity requires organized, spatially nuanced interactions between components of the immune tumor microenvironment (iTME). Understanding this coordinated behavior in effective versus ineffective tumor control will advance immunotherapies. We re-engineered co-detection by indexing (CODEX) for paraffin-embedded tissue microarrays, enabling simultaneous

Membrane contact sites between virtually any known organelle have been documented and, in the last decades, their study received momentum due to their importance for fundamental activities of the cell and for the subtle comprehension of many human diseases. The
