Azido-PEG3-SS-PEG3-azide is a PEG-based PROTAC linker designed for use in the synthesis of PROTACs. This compound functions as a click chemistry reagent, featuring an Azide group that can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with molecules containing Alkyne groups. Additionally, it can engage in strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups. PROTACs themselves are agents that utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- A PEG-based PROTAC linker.
- Used in the synthesis of PROTACs.
- Functions as a click chemistry reagent.
- Contains an Azide group.
- Can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with Alkyne-containing molecules.
- Can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with DBCO or BCN-containing molecules.

Bis-PEG3-NHS ester is a non-cleavable PEG-based bifunctional linker containing two N-hydroxysuccinimide (NHS) ester reactive groups used for bioconjugation and antibody-drug conjugate (ADC) construction. The three-unit PEG spacer increases hydrophilicity and solubility, while the NHS esters enable efficient coupling to primary amines on proteins and peptides.
- Non-cleavable 3-unit PEG linker for stable conjugation.
- Contains two NHS ester groups for bioconjugation to primary amines.
- Improves solubility and hydrophilicity of conjugates.
- Available in multiple package sizes, including 500 mg.
- Provided with SDS, COA, and product data sheet for quality and safety information.

Calcein (tetraethyl ester) is a membrane-permeant fluorescent dye used to label live cells in viability assays, cell tracing, and fluorescence microscopy. The esterified form crosses cell membranes and is hydrolyzed intracellularly to fluorescent calcein, producing strong green fluorescence for imaging and quantitative measurements.
- Membrane-permeant fluorescent dye for live-cell labeling
- Intracellular conversion yields bright green fluorescence
- High purity suitable for research use (99.5%)
- Molecular weight 734.75 g/mol
- CAS number 1170856-93-5 for identification
- Available in small quantities for laboratory assays

Bis-PEG3-NHS ester is a noncleavable, three-unit polyethylene glycol (PEG) linker bearing N-hydroxysuccinimide (NHS) ester termini for amine-directed bioconjugation and antibody-agent conjugation applications.
- Provides two NHS ester termini for efficient amine coupling.
- Three-unit PEG spacer increases hydrophilicity and reduces steric hindrance.
- Noncleavable design yields stable conjugation in antibody-drug conjugate constructs.
- High purity suitable for research applications.
- Stable as a powder at -20°C for long-term storage; limited stability in solution.
