80-O16B
Instructions for Use
Product information
80-O16B is a disulfide bond-containing ionizable cationic lipidoid. It has been used in the generation of lipid nanoparticles (LNPs) for the delivery of CRISPR complementary single-guide RNA (sgRNA) and Cas9 for genome editing in mice. LNPs containing 80-O16B conjugated to phenylboronic acid (PBA) and encapsulating an mRNA reporter increase luciferase reporter expression in HeLa cancer cells.2 LNPs containing 80-O16B conjugated to PBA and encapsulating p53 mRNA decrease the viability of DU145 prostate and SiHa and HeLa cervical cancer cells.

Formulation & study context
Literature information refers to the cited study and its particular formulation. Administration routes are research context, not clinical instructions or a guarantee of performance.
A complete product-specific formulation has not been verified. No standard ratio is substituted.
| N/P ratio | Not reported in the verified record |
| Cargo | Not available in the verified record |
| Administration route | Not available in the verified record |
| Animal model | Not available in the verified record |
| Formulation process | Not available in the verified record |
N/P is the molar ratio of specified lipid nitrogen groups to nucleic-acid phosphate groups. A lipid:cargo mass ratio is a different quantity and must not be used as N/P.

Provided that storage conditions are as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 1 year.
Wherever possible, prepare and use solutions on the same day. If stock solutions must be prepared in advance, store them as aliquots in tightly sealed vials at -20°C. Generally, these will be usable for up to one month.
Before use, and prior to opening the vial, allow the product to equilibrate to room temperature for at least 1 hour.
