Frequently Asked Questions
How do I choose Polyethylene Glycol (PEGs & PEOs) for my workflow?
Match reactivity, spacer length, photophysical properties, and conjugation chemistry to your target. Consider water solubility, cell permeability, and downstream detection method.
What specifications matter for Polyethylene Glycol (PEGs & PEOs)?
Functional group reactivity, purity (HPLC), spacer length, optical properties (excitation/emission for fluorophores), water solubility, and storage stability. Light sensitivity is critical for photoactivatable compounds.
Are bifunctional and bioorthogonal variants available?
Yes. Hetero-bifunctional linkers, click chemistry reagents (azide/alkyne), and bioorthogonal handles are available for two-step labeling and conjugation workflows.
How should light-sensitive compounds be handled?
Store light-sensitive products in amber containers, protected from ambient light. Many products are stable at -20°C in the dark. Use minimal light exposure during weighing and dilution.
