일반 설명
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.
애플리케이션
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

Hypophosphataemia is frequently encountered in dairy cows during early lactation. Although supplementation of P is generally recommended, controversy exists over the suitability of oral P supplementation in animals with decreased or absent rumen motility. Since the effects of transruminal P

Elevated serum phosphate has emerged as a major risk factor for vascular calcification. The sodium-dependent phosphate cotransporter, PiT-1, was previously shown to be required for phosphate-induced osteogenic differentiation and calcification of cultured human vascular smooth muscle cells (VSMCs), but its
