CAP 2 (hydrochloride)
Instructions for Use
Product information
CAP 2 is a unique ionizable lipid featuring a bicholesterol structure connected by a phosphate linker with an amino terminus. This design enables efficient in vivo delivery of both mRNA and saRNA via LNPs. In a Dmc1-deficient mouse model of male infertility, saRNA-encoded Dmc1 delivered by CAP 2 LNPs demonstrated prolonged protein expression in testicular tissue compared to mRNA formulations. The treatment restored spermatogenesis, improving germ cell maturation, seminiferous tubule morphology, and ultimately yielding functional sperm capable of fertilization.

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.
