m-PEG24-NHS ester is a methoxy-terminated polyethylene glycol (PEG) linker functionalized with an N-hydroxysuccinimide (NHS) ester. The NHS group reacts with primary amines to form stable amide bonds, enabling bioconjugation and linker installation in medicinal chemistry workflows such as PROTAC assembly. The reagent is provided with high purity for research applications.
- Methoxy-terminated PEG24 linker with NHS ester reactivity.
- Reacts with primary amines to form stable amide bonds.
- Compatible with PROTAC synthesis and general bioconjugation.
- High purity suitable for research use.
- Molecular weight approximately 1214.39 g·mol⁻¹.

Cardiac muscle myosin is a hexamer consisting of two heavy chain subunits, two light chain subunits, and two regulatory subunits. This gene encodes the alpha heavy chain subunit of cardiac myosin. The gene is located approximately 4kb downstream of the gene encoding the beta heavy chain subunit of cardiac myosin. Mutations in this gene cause familial hypertrophic cardiomyopathy and atrial septal defect 3.
