Oxazine 1 perchlorate is a symmetric cationic dye (λex=653 nm, λem=666 nm).
体外研究 (In Vitro)
Oxazine 1 perchlorate (OX1) absorbs and emits light at about 653 and 666 nm in dilute aqueous solutions, respectively. It is soluble over a very wide range of polar solvents. The optical spectrum of Oxazine 1 perchlorate typically possesses an intense absorption band (λmax), which is neighbored by a shoulder at shorter wavelengths. Oxazine 1 perchlorate appears to exist almost in its monomeric form at concentrations below about 1×10-4 M in aqueous solutions. As it is expected, similar to polar ordinary liquid solvents, Oxazine 1 perchlorate shows only single fluorescence band in polar anisotropic media[1].

Kinase Assay [1]
Oxazine 1 perchlorate doped liquid crystal samples are prepared from a pair of quartz sheets sandwiched exactly at known gap and sealed. The introduction of the dissolved Oxazine 1 perchlorate in nematic solvents is achieved by capillary action. Oxazine 1 perchlorate concentrations are chosen to be 1×10−5 M for all the liquid samples. Oxazine 1 perchlorate is studied in the nematic media up to a concentration of about 0.1%, w/w. The absorption spectra of Oxazine 1 perchlorate are recorded on a double beam spectrophotometer over a wavelength range 300 to 800 nm combined with a cell temperature controller[1].

TMRM Perchlorate is a cell-permeant cationic lipophilic red fluorescent dye (λex=530 nm, λem=592 nm).
体外研究 (In Vitro)
TMRM Perchlorate is a fluorescent probe (excitation, 530±21 nm; emission, 592±22 nm). The fluorescence signal in the presence of TMRM Perchlorate shows a slight decrease after the addition of glutamate, indicative of increased polarization of the mitochondrial inner membrane. In the presence of TMRM Perchlorate (2 μM) the coupled respiration with Complex I substrates or upon the addition of Complex II substrate is decreased by 27%[1]. Exposure of hippocampal cultures to low concentrations of TMRM Perchlorate (50 to 500 nM) for 1 to 3 hours results in selective staining of mitochondria in both neurons and the underlying glial cells. Exposure of hippocampal cultures to high concentrations of TMRM Perchlorate (1 to 25 µM) stains mitochondria selectively and quickly, reaching a plateau after 5 to 10 min. Low concentrations of TMRM Perchlorate (50 to 200 nM) do not induce apoptosis, whereas higher concentrations (0.5 and 2.5 µM) enhance apoptosis (KD = 500 nM)[2].

Cell Assay [1]
Cultures are exposed to Millipore-filtered solutions (0.22 µm) containing TMRM Perchlorate for 1 hr at 37°C (except the experiment involving different durations of exposure to TMRM Perchlorate). After treatment, solutions are removed and growth media reapplied under sterile conditions, and cultures are post-incubated for 18 hours at 37°C (except for the experiment involving analysis at different time points after exposure). Cells are then stained with 2 mg/mL bisbenzimide for 20 min at room temperature. Coverslips are subsequently washed in saline and imaged using 2P microscopy. Apoptotic cells are identified as brightly fluorescent nuclei under UV excitation indicating DNA fragmentation. Cell survivability is calculated as the percentage of live, unstained cells (±SD) in five microscopic fields per treatment[1].

Cresyl Violet perchlorate is a red fluorescent stain, which can be used to stain neurons.
体外研究 (In Vitro)
The estimated total number of SG neurons is 27,485±3251 and 26,705±1823 in the PV and Cresyl Violet perchlorate (CV) stained sections, respectively. There is no significant difference between them (p=0.552). Therefore, Cresyl Violet perchlorate staining is simpler and more cost effective when estimates neuronal number. Although PV stains spiral ganglion neurons (SGNs) with a greater intensity and provides a functional status, its tedious protocol limits its use for quantification. Total RC volume is estimated using probe and it is found that an average RC volume of 2.162±0.35 mm3 and 1.82±0.33 mm3 in Cresyl Violet perchlorate stained and PV immunostained sections, respectively. Volume of neurons is estimated using nucleator probe and it is 3487.63±951 μm3 and 3740.1±784 μm3 in CV stained and PV immunostained sections, respectively. Similarly, volume of neuronal nucleus is also estimated using nucleator probe and it is found to be 131.68±50 μm3 and 126.51±33 μm3 in CV stained and PV immunostained sections, respectively[1].

Cell Assay [1]
Cochlear sections containing SGNs are placed in 24 wells plates containing PBS (pH 7.4) and stored at 4°C. The sections are then used for Cresyl Violet perchlorate (CV) and immunohistochemical (IHC) staining. Every 7th section is stained with Cresyl Violet perchlorate (1%), dehydrated with ascending grades of alcohol, cleared with xylene, mounted with DPX and observed under microscope. Approximately 12-13 Cresyl Violet perchlorate stained sections from each specimen are used for stereology. None of these cases show any histopathological changes under the light microscope. Estimation of the total volume of the Rosenthal canal (RC), total number of SGNs (optical fractionator probe) and the volume of the soma and their nucleus (nucleator probe) is done with software[1].

生物活性
DiD perchlorate is a far-red fluorescent lipophilic cyanine dye. DiD perchlorate can rapidly and stably integrate into the phospholipid cell membrane. DiD perchlorate is used to cells tracking[1][2][3].
体内研究 (In Vivo)
Two weeks after injection of stained cells, a single, bright, DiD perchlorate (DiD)-positive cells located between 15 to 40 µm from the endosteum is found. Results reveal a progressive appearance of cell clusters of decreased dye intensity, consistent with the partitioning of DiD perchlorate label on cell division[3].

Animal Administration [1]
1 to 5×105 cells per mL HSPCs are stained with 5 μM DiD perchlorate (DiD) or 7.5 μM DiI in PBS without serum for 10 min at 37°C, washed once in PBS and immediately injected into the tail vein of recipient mice. Unless stated differently, each imaged CD45.2 mouse receive 8,000 to 15,000 labelled CD45.1 HSPCs together with 3 to 5×105 CD45.2 supportive whole bone-marrow mononuclear cells to ensure survival[1].
