TCL053
Instructions for Use
Product information
TCL053 is an ionizable amino lipid.1 It has been used in the generation of lipid nanoparticles (LNPs) and has a pKa value of 6.8. LNPs containing TCL053 and encapsulating mRNA encoding the Cas9 nuclease, in combination with LNPs containing TCL053 and encapsulating single-guide RNA (sgRNA) targeting the Rosa26 locus, have been used to induce CRISPR-mediated gene editing in the mouse gastrocnemius muscle.TCL053 is an ionizable lipid that has received FDA approval for preparing mRNA vaccines. It is a three-tailed ionizable lipid to overcome the disadvantage of nonrepeatable administration of AAV vectors. In addition, combined with limb perfusion administration, TCL053 iLNPs could transiently deliver CRISPR-Cas9 mRNA and sgRNA to multiple muscle tissues, reducing immunogenicity and increasing the safety of iLNPs. It is great progress for treating Duchenne muscular dystrophy and other diseases that require multiple doses.

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.

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.
