General description
Derived from the naturally occurring amino acid l-lysine, Poly-L-lysine is available in various forms, allowing for customization in terms of molecular weight and shape. As a synthetic positively charged polymer, it exists in two enantiomers, poly-D-lysine and poly-L-lysine, both of which have their unique applications.
In formulation research, Poly-L-lysine proves to be valuable in nucleic acid delivery. Its positive charge, attributed to the ε-amine on its side chain at physiological pH, enables it to condense plasmid DNA effectively based on salt concentration. While Poly-L-lysine appears suitable for gene delivery, unmodified versions have been associated with low transfection efficiency and cytotoxicity.
In conclusion, Poly-L-lysine offers a multifaceted solution in cell culture and formulation research, enhancing cell adhesion, enabling gene delivery, and contributing significantly to advancements in biochemical and cell biology research.

How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
