Sigma Aldrich Fine Chemicals Biosciences Phalloidin Atto 390 suitab
Atto 390 Phalloidin is a novel fluorescent label with a coumarin structure. The dye is intended for application in the area of life science e.g. labeling of DNA RNA or proteins. Characteristic features of the label are high fluorescence quantum yield large Stokes-shift good photostability and low molecular weight.Phalloidin is a fungal toxin isolated from the poisonous mushroom Amanita phalloides. Its toxicity is attributed to the ability to bind f actin in liver and muscle cells. As a result of binding phalloidin actin filaments become strongly stabilized. Phalloidin has been found to bind only to polymeric and oligomeric forms of actin and not to monomeric actin. The dissociation constant of the actin-phalloidin complex has been determined to be on the order of 3 x 10-8. Phalloidin differs from amanitin in rapidity of action at high dose levels death of mice or rats occurs within 1 or 2 hours.

Sigma Aldrich Fine Chemicals Biosciences SMCTM Human IL 17A High Se
The SMC(TM) human IL-17A High Sensitivity Immunoassay Kit contains all reagents required to perform the assay. This assay takes advantage of a standard immunoassay workflow configured in a standard plate format.Assay protocols are similar to existing sandwich ELISA methods with two key differences1) Elution buffer disrupts the sandwich separating the labeled detection antibody for quantification.2)The Erenna and SMCxPRO(TM) immunoassay systems detect analytes using Single Molecule Counting (SMC(TM)) technology.
Medchemexpress LLC Mal-PEG10-NHS ester | 3055858-73-3 | 98.0% | 706.73 | 50 MG
Mal-PEG10-NHS ester is a PEG-based PROTAC linker that can be utilized in the synthesis of PROTACs. PROTACs consist of two different ligands connected by a linker, with one ligand for an E3 ubiquitin ligase and the other for the target protein, functioning by exploiting the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- PEG-based PROTAC linker
- Utilized in the synthesis of PROTACs
- Selectively degrades target proteins through the ubiquitin-proteasome system
- High purity: 98.0%
- Molecular weight: 706.73
- Appearance: colorless to light yellow oil
- Solubility: 100 mg/mL in DMSO

AdipoGen Fluorescein dioctadecanoate
Chemical. CAS 920269-51-8. Formula C56H80O7. MW 865.23. Fluorescein dioctadecanoate is a non-fluorescent hydrophobic fluorescein derivative that can pass through the cell membrane whereupon intracellular esterases hydrolyze the dioctadecanoate group producing the highly fluorescent product fluorescein. The fluorescein molecules accumulate in cells. Fluorescein dioctadecanoate is a fluorogenic substrate for C18 esterase that generates green fluorescence upon esterase cleavage. Spectral Data lambdaEx 497nM, lambdaEm 516nm. Extinction coefficient 80000 cm-1 M-1.
