PEG (Polyethylene glycol) modified cholesterol esterase (PEG Cholesterol Esterase) isone of our premier cholesterol esterase conjugates. Cholesterol esterase is an enzyme that catalyzes the hydrolysis of cholesterol esters into their sterol components and fatty acids. Cholesterol esterase has clinical applications in the determination of serum cholesterol combined with other enzymes. PEG modified cholesterol esterase shows better stability with good reactivity. All our labeled cholesterol esterase products were performed under mild reaction conditions to retain their maximum bioactivity. These conjugates were further purified by chromatography to ensure adequate applications both in-vitro and in-vivo. Conjugate ration: 20~50 peg5000/monomer. solubility: soluble in aqueous buffer.

Cholesterol (For Injection)
Cholesterol is a fatty, waxy substance classified as a steroid lipid. Produced by all animal cells, cholesterol is an essential structural component of animal cell membranes, where it helps to regulate both fluidity and permeability. Cholesterol also serves as an important precursor for the biosynthesis of steroid hormones (like estrogen and testosterone), bile acids, and Vitamin D. Applications: In addition to its role in physiology, cholesterol serves many roles in pharmaceuticals and cosmetics. it is used as a raw material for the industrial manufacture of vitamin d3 and hormonal medications. cholesterol is widely used in drug-delivery, especially in liposomes. liposomes are lipid vesicles used to deliver drugs in a protective capsule so that they reach their target tissue intact. cholesterol is added to many liposomal compositions to "tighten" the lipid bilayer. it is also added to many luxury skin care products because it is an effective emollient.

Cholesterol (from animal)
Cholesterol (from animal) is the major sterol in mammals. It is making up 20-25% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol (from animal) plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins[1][2]. Cholesterol (from animal) is also an endogenous estrogen-related receptor α (ERRα) agonist[3]. Uses: Scientific research. Category: Signaling pathways. CAS No. 57-88-5.
