Nissl Staining Solution (Thionin Method) is a neural tissue staining solution with thionin as the core component, which stains Nissl bodies purplish blue and nuclear chromatin blue. Nissl Staining Solution (Thionin Method) relies on positively charged thionin molecules to specifically bind to the negatively charged nucleic acid components in the rough endoplasmic reticulum inside Nissl bodies, and achieves differential staining by regulating pH through a buffer system. Nissl Staining Solution (Thionin Method) has pH-dependent staining selectivity; it exhibits the highest staining specificity for neuronal Nissl bodies under pH 3.65 conditions, and can efficiently label glial processes under pH 4.6 conditions .

Cortisol-selective aptamer is a nucleic acid that selectively binds to cortisol. Cortisol-selective aptamer undergoes conformational transition upon binding to cortisol, inducing fluorescence quenching of quantum dots. Cortisol-selective aptamer can be integrated into gold nanoparticle colorimetric assays in buffer solutions to distinguish cortisol from other biomarkers of stress and liver dysfunction .
Cat. No.: HY-K3038
MCE Sodium Bicarbonate Solution (7.5%) is designed to adjust the bicarbonate buffering system of cell culture media. Under appropriate CO2 culture conditions, sodium bicarbonate helps maintain physiological pH, neutralizes acidic metabolites produced by cellular metabolism, and provides a stable environment for cell growth. It also supplies bicarbonate ions required for certain cellular metabolic processes.

CMTDP is a Fluorescent probe for detecting local polarity changes around the Cys34 domain of bovine serum albumin during pH-induced N→B conformational transition. It is a thiol-specific and polarity-sensitive probe; it covalently labels the free cysteine residue at position 34 (Cys34) of bovine serum albumin, and its fluorescence maximum emission wavelength shifts in response to solvent polarity, but not to pH and temperature. When labeled to BSA, as the local polarity around the Cys34 domain increases with rising pH, the probe shows a bathchromic shift in fluorescence emission wavelength and a decrease in fluorescence intensity, which allows quantification of the local polarity change via the relationship between emission wavelength shift and dielectric constant. CMTDP itself has absorption peaks at ~392 and 508 nm, and CMTDP-labeled BSA has excitation maxima at 376 and 470 nm at pH 6.0, with the shorter-wavelength excitation peak red-shifting as pH increases while the longer one remains stable; when excited at 470 nm, the fluorescence emission maximum shifts from 570 nm at pH 6.0 to 577 nm at pH 9.1, while free CMTDP at pH 7.4 has an emission maximum at 621 nm. The excitation/emission wavelengths for CMTDP-labeled BSA are Ex/Em = 376/570 nm at pH 6.0, Ex/Em = ~376+/573 nm at pH 7.4, Ex/Em = ~376+/575 nm at pH 8.0, Ex/Em = ~376+/577 nm at pH 9.1, and for free CMTDP at pH 7.4, Ex/Em (when excited at 470 nm) = 470/621 nm[1].

NtHzBtd is a fluorescent probe for detecting Fe 3+. NtHzBtd is applicable to the selective fluorescent detection of Fe 3+ ions and live cell imaging studies. NtHzBtd can selectively coordinate with Fe 3+ to form a 1:1 complex, triggering chelation enhanced quenching (CHEQ) and intramolecular charge transfer (ICT) processes, which result in fluorescence turn-off, thereby enabling sensitive detection of Fe 3+ and live cell fluorescence imaging. After binding to Fe 3+, NtHzBtd reduces fluorescence intensity, exhibits a rapid response property, with a limit of detection of 0.036 μM and a response time of approximately 55 s. The detection wavelengths are Ex/Em = 334/401 nm (solution system) .
