Parethoxycaine (Intracaine) is an ester-type local anesthetic that possesses dual activities as a non-selective inhibitor and agonist potentiator in smooth muscle, while acting as a mixed-type inhibitor of cytochrome c oxidase at the enzyme level. Parethoxycaine non-competitively inhibits the contraction of guinea pig ileal longitudinal muscle by interfering with transmembrane Ca 2+ transport (blocking K +/CD responses in an equi-effective manner), and potentiates norepinephrine (NA) responses in rat vas deferens by blocking NA uptake and promoting Ca 2+ mobilization (increasing the maximum amplitude without affecting K + responses). Parethoxycaine inhibits the activity of purified cytochrome c oxidase in a concentration-dependent manner, and can be used in research focusing on Ca 2+ signal transduction, smooth muscle contraction regulation, and mitochondrial energy metabolism .

5-TAMRA cadaverine can used to modify carboxylic acid group in the presence of activators (e.g. EDC, or DCC) or activated esters (e.g. NHS esters) through a stable amide bond. It also can be reversibly coupled to aldehydes and ketones to form a Schiff base – which can be reduced to a generate stable amine derivative by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaCNH3). Although the mixed isomers of 5(6)-TAMRA cadaverine is a preferred, routinely used orange-fluorescent dye for staining proteins, it is rearly used for labeling peptides and nucleotides. Purification of 5(6)-TAMRA labeled peptide and nucleotides might be troublesome due to significant signal broadening in HPLC purification. Peptides and nucleotides labeled with a single isomer TAMRA usually give better resolution in HPLC purification that is often required in the conjugation processes.

5-Carboxyrhodamine 110 NHS Ester is the nonsulfonated analog of the BP Fluor 488 dye. The amine-reactive 5(6)-Carboxyrhodamine 110 NHS Ester can be used to create bright and photostable green-fluorescent bioconjugates with excitation/emission maxima ~502/527 nm. For many applications, the dye is preferred over 5-(6)-carboxyfluorescein NHS ester or FITC because of its exceptional photostability and fluorescence insensitivity to pH (4-9). Although the mixed isomers of Carboxyrhodamine 110 NHS Ester preferred, routinely used fluorescent dye for labeling proteins, peptides and nucleotides, purification of peptide and nucleotides labeled with 5(6) isomers might be troublesome due to significant signal broadening in HPLC purification. Peptides and nucleotides labeled with a single isomer usually give better resolution in HPLC purification that is often required in the conjugation processes.

Cremophor EL-10 is a nonionic polyoxyethylene castor oil surfactant with multiple functions including organic solubilizer, mixed zinc anode corrosion inhibitor and dendrite growth inhibitor. By forming a physical barrier to block electrolyte contact and constructing oriented hydration channels to reduce the desolvation energy barrier of Zn 2+ , Cremophor EL-10 achieves a corrosion inhibition efficiency of over 99%. Cremophor EL-10 exerts no significant effects on the mitochondrial activity and cell viability of epithelial cells, making it suitable for in vitro drug delivery and biopharmaceutical research at concentrations ≤10% v/v. However, Cremophor EL-10 may induce sustained non-endothelium-dependent contraction in rat aortic rings and exert concentration-dependent inhibitory effects on acetylcholine-induced endothelium-dependent relaxation responses .

MCE Weigert Elastin Staining Kit combines Weigert Resorcinol Fuchsin Staining Solution with Van Gieson (VG,Elastin Fiber Staining Reagent B,mixed) Staining Solution. Weigert Resorcinol Fuchsin Solution is mainly used for staining elastic fibers, Van Gieson (VG) Solution is used for collagen fiber staining. The principle of VG staining is based on differences in the size of anionic dye molecules and the permeability of tissues. Picric acid (PA) has the smallest molecular weight and preferentially enters dense structures. Ponceau Red or acid fuchsin has a relatively larger molecular weight and primarily binds to collagen fibers, while light green has the largest molecular weight and stains other tissue components. After VG staining, collagen fibers appear red, while muscle fibers and cytoplasm appear yellow, enabling a clear distinction between tissue components.

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 .

DJK-5 is an antimicrobial peptide that targets and degrades guanosine pentaphosphate and tetraphosphate (pppGpp and ppGpp). DJK-5 kills bacteria within dentinal tubules, dental plaque and preformed oral biofilms, delays biofilm recovery, reduces the abundance of extracellular polysaccharides and the structural integrity of biofilm matrices, and inhibits the formation and biomass accumulation of dental plaque biofilms. DJK-5 permeabilizes bacterial membranes, induces bacterial morphological changes, inhibits bacterial growth, and exerts a synergistic effect on bacterial biofilms when used in combination with traditional antibiotics and Colistin (HY-113678). DJK-5 exhibits protease resistance and broad-spectrum antibiofilm activity, though its activity decreases in fetal bovine serum. DJK-5 can be used in studies of pulpitis, mixed biofilm infections, skin abscesses, dental caries, infections associated with failed root canal therapy, and Pseudomonas aeruginosa biofilm-related respiratory tract infections .

Synonyms: Orexin A (17-33) (human, mouse, rat, bovine)
OXA (17-33) (Orexin A (17-33) (human, mouse, rat, bovine)) is the shortest active orexin peptide that selectively targets OX1 (EC50=8.29 nM), with 23-fold selectivity for the OX1 receptor over the OX2 receptor. The activity of OXA (17-33) depends on the Tyr17, Leu20, Asn25, His26 residues and the spatial conformation of the α-helix. OXA (17-33) activates signaling pathways involving inositol-1,4,5-trisphosphate receptor (IP3R), phospholipase D (PL-D) and choline-Sigma-1R, thereby increasing the cytoplasmic Ca 2+ level in nucleus accumbens neurons, an effect that is blocked by Sigma-1R antagonists. OXA (17-33) serves as an important biological probe for investigating the function of the OX1 receptor. OXA (17-33) can be modified via incorporation of mixed disulfide bonds of homocysteine and cysteamine, and is widely used in studies related to insomnia and narcolepsy .
