Am-KYa12K4

Am-KYa12K4 is a peptide-ionizable lipid (PIL) that can be incorporated into lipid nanoparticles (LNPs) to deliver mRNA to the thymus with high specificity. LNPs formulated with Am-KYa12K4 significantly enhance mRNA expression in the thymus.

제품 설명

In Vivo

Am-KYa12K4 LNPs (0.3 mg/kg; i.v.; single dose) achieve thymus-selective mRNA delivery with 66.4% organ specificity in healthy female C57BL/6 mice^[1].
Am-KYa12K4 LNPs combined with 126ts-Luc mRNA (1.0 mg/kg; i.v.; single dose) achieve enhanced thymus-selective mRNA delivery with 82.4% organ specificity in healthy female C57BL/6 mice^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

C57BL/6 (female, 6-8 weeks old, 18-20 g)^[1]
Dosage:

0.3 mg/kg Luc mRNA
Administration:

i.v.; single dose
Result:

Mediated luciferase expression with 66.4% specificity in the thymus, with reduced expression in all other evaluated organs.
Reached thymus radiance of ~1×10⁶ photons s^-1 cm^-2 sr^-1, which was significantly higher than radiance in the heart, liver, lungs, spleen, and kidneys.

Animal Model:

C57BL/6 (female, 6-8 weeks old, 18-20 g)^[1]
Dosage:

1.0 mg/kg 126ts-Luc mRNA
Administration:

i.v.; single dose
Result:

Mediated luciferase expression with 82.4% specificity in the thymus, with minimal expression in other organs.
Reached thymus radiance of ~3.5×10⁵ photons s^-1 cm^-2 sr^-1, which was significantly higher than radiance in all other evaluated organs.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
