Cat. No.: HY-D3075
CAS No.: 2490504-23-7
Target:
Research Areas:
TPE-2E N-oxide is a fluorescent probe used for hypoxia detection and tumor hypoxia imaging. Due to its active intramolecular motion, TPE-2E N-oxide shows no fluorescence in aqueous solution. In hypoxic environments, its N-oxide group undergoes two-electron reduction by CYP450 reductase and other heme protein reductases expressed under hypoxia, forming hydrophobic aggregates that trigger aggregation-induced emission through the restriction of intramolecular motion. TPE-2E N-oxide exhibits selective lipid droplet localization in cells. The absorption wavelength of TPE-2E N-oxide in dichloromethane is 313 nm; in a 99% hexane/dichloromethane mixed system, its excitation wavelength is 330 nm and emission wavelength is 460 nm. For in vitro cell imaging, excitation is performed at 405 nm, with an emission wavelength range of 430-560 nm .
Cat. No.: HY-K1026
MCE TBS Powder (1 L of 1×) consists of NaCl, KCl and Tris, and is widely used as washing buffer in immunocytochemistry, FISH or ELISA, and can also be used for antibody dilution and preparation of blocking solution. The 20 pouches are defined as the base specification. All larger sizes correspond to incremental volumes of this base.
Cat. No.: HY-DY2027

Research Areas:
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 .
Cat. No.: HY-188092
Target:
Research Areas:
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.
Cat. No.: HY-D3200
CAS No.: 3112200-59-3
Cat. No.: HY-D3582
Target:
Research Areas:
AF633 C5 Maleimide is a fluorescent dye used for surface protein labeling of extracellular vesicles and peptide labeling. AF633 C5 Maleimide covalently binds to protein thiol residues under neutral pH conditions (6.5-7.5), enabling visualization and quantitative analysis of extracellular vesicle uptake by target cells. AF633 C5 Maleimide undergoes maleimide-cysteine conjugation with cysteine residues on peptides in acetonitrile-water buffer solution, supporting detection of peptide-functionalized gold nanorods via confocal laser scanning microscopy, as well as tracking their cellular uptake and localization .

The Nobel Prize winning "Click Chemistry" can be used like this!A suitable model is crucial in drug screening experiments. Organs can mimic the three-dimensional functional structure of internal organs, have similar spatial organization to corresponding organs, maintain some key characteristics, and reproduce some physiological functions. They are widely used for modeling and personalized drug screening physiological functions.2025-02-06
