General description
Application
It can be used as a precursor to prepare polyelectrolyte multilayers for the promotion of cell adhesion and growth on implant surfaces.
PEI can act as a reactive template and stabilizing agent in the preparation of metal nanoparticles in aqueous media. The amino groups in the PEI can coordinate with metal ions dissolved in water and reduce their aggregation capability. This results in the formation of smaller nanoparticles.
Features and Benefits
- It has repetitive structural units and aflexible polymer chain.
- Due to the accessibility of a huge number ofamino groups on PEI, it can be modified or functionalized for specific featuressuch as sensitivity, specificity, and biocompatibility.
- Highwater solubility.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
