buffer

MOPS sodium salt (MOPS-Na) is a novel stabilizer maintaining the pH of mammalian cell culture media. It used as a buffer for the native structure of BSA against thermal denaturation.MOPS sodium salt(3-(N-morpholino)propanesulfonic acid sodium salt) is commonly used as a buffer in biology.

5-ROX (5-Carboxy-X-rhodamine), a rhodamine dye, exhibits strong fluorescence in aqueous buffer with an excitation wavelength (λexit) of 580 nm (ε = 3.6×10^4 (M·cm)) and an emission wavelength (λemit) of 604 nm (ϕ = 0.94).

3,6-diacetoxy Phthalonitrile is a fluorescent probe for monitoring intracellular pH by flow cytometry in living cells. It rapidly crosses cell membranes and is cleaved by cytosolic esterases to form the fluorescent pH indicator 2,3-dicyano-hydroquinone (DCH), which is excited at UV wavelengths. DCH can be excited at 351 nm, with pH-dependent emission in the range of 450-476 nm (pH 5.0-10.0) using a potassium-based buffer.

Quin-2 is a high-affinity fluorescent calcium indicator (Kd = 115 nM for calcium). It displays high selectivity for calcium, as it is not affected by sodium gradients, membrane potential, or intracellular pH. High affinity probes like quin-2 are ideal for monitoring low levels of calcium, as are found in resting cells. Loadings of up to 2 mM quin-2 are without serious toxic effects, so quin-2 may be used to buffer intracellular calcium transients. Excitation emission maxima for quin-2 are 339 and 492 nm, respectively.

5,5'-Dibromo BAPTA tetrapotassium, a calcium chelator, can be formulated into a buffer with a defined calcium ion concentration, allowing for precise control of calcium ion levels both intracellularly and extracellularly, and is used in studies of calcium physiological activity [1].

BDP FL tetrazine, a BDP dye linker with methyltetrazine groups, can be prepared as a 1 mM stock solution in DMSO and diluted to 1 μM with PBS buffer before use.

Thiazole orange dimer YOYO-1 is a green fluorescent dye used for DNA staining. It is a tetracationic homodimer of oxazole yellow (YO) and is typically provided as a tetraiodide salt. In aqueous buffer, the free YOYO-1 dye (λmax 458 nm; λmax 564 nm) exhibits low fluorescence quantum yield, but upon binding to double-stranded DNA through diintercalation, its fluorescence intensity increases by 3200 times (λmax 489 nm; λmax 509 nm).

1) Non-toxicity: The unique oiliness and high molecular weight characteristics of CelRed prevent it from penetrating cell membranes into cells, and Ames test results also show that the mutagenicity of CelRed dye is much less than EB. 2) High sensitivity:
