- Extra Details:
- Polyethylene glycols (PEGs) are synthetic and hydrophilic polymers. They are linear or branched and contain a reactive end group, such as acrylate, methacrylate, dibenzocyclooctynol, or vinyl sulfonate, for covalent attachment to macromolecules or linkers. The opposite end group of PEGs is commonly a methyl group (methoxy PEG), however, hydroxy, amino, butoxy, and tert-butoxy end groups have also been used. PEGs are non-toxic and are commonly used to prolong the in vivo circulation time of pharmaceutical agents. Free PEGs are non-immunogenic but become immunogenic when conjugated to a drug delivery nanosystem (DDS) or a macromolecule. Immunogenicity of PEGs varies based on polymer length and branching, end group composition, and chemical nature of the PEG acceptor structure. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry Other applications not tested. Recommended Dilutions: ELISA: 0.01-3ug/ml Immunohistochemistry (paraffin): 0.5-2ug/ml Western Blot: 0.05-1ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt.
