AHP1254 recognises cholesterol 24-hydroxylase (CYP46A1), a 58 kDa member of the Cytochrome P450 family, expressed in the brain. CYP46A1 converts cholesterol into the biologically active oxysterol and 24(S)-hydroxycholesterol, in the first step of the enzymatic degradation of cholesterol in the brain. CYP46A1 is also thought to play a role in the metabolism of neurosteroids and drugs that can cross the blood-brain barrier and are targeted to the central nervous system.
P450 enzymes are divided into two groups: steroidogenic and xenobiotic. The latter group is comprised of three families 1, 2 and 3. The xenobiotic p450's are involved in most oxidative drug metabolism. Work in this area is ongoing but studies suggest that all known drug metabolism is mediated by family members: CYP3A, CYP2D6, CYP1A2, CYP2C9/10, CYP2C19 and CYP2E1.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
AHP1254 detects a band of approximately 58kDa in human Alzheimer diseased brain lysates.
Storage
Store at +4oC or at -20oC if preferred.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
18 months from date of despatch.
Antiserum Preparation
Antisera to cholesterol 24-hydroxylase (CT) were raised by repeated immunisations of goats with highly purified antigen.
