R-MU-0047	8arm-PEG-DBCO	8 arm-Polyethylene glycol-DBCO, 8 arm-PEG-DBCO, DBCO-PEG-8 arm from ruixi The dibenzocyclooctyne group (DBCO) reacts with molecules containing azide groups (–N3) in a Copper-free Click Chemistry. DBCO has very high reaction selectivity toward azide, enabling its use in modifying biomolecules including peptide, protein, enzyme, live cells, whole organisms etc. At physiological temperature and pH ranges, the DBCO group does not react with amine or hydroxyl, and DBCO also reacts with the azide group much faster than with free thiol groups. DBCO is also known as ADIBO (= Azadibenzocyclooctyne) or DIBAC (= Dibenzoazacyclooctyne).	price>

R-R-0955	Talfirastide acetate	Angiotensin 1-7 (Ang-(1-7)) acetate/CAS No.2855063-75-9 is an endogenous heptapeptide from the renin-angiotensin system (RAS) with a cardioprotective role due to its anti-inflammatory and anti-fibrotic activities in cardiac cells. Angiotensin 1-7 acetate inhibits purified canine ACE activity (IC50=0.65 μM). Angiotensin 1-7 acetate acts as a local synergistic modulator of kinin-induced vasodilation by inhibiting ACE and releasing nitric oxide. Angiotensin 1-7 acetate blocks Ang II-induced smooth muscle cell proliferation and hypertrophy and shows antiangiogenic and growth-inhibitory effects on the endothelium.	price>
