AHP1304 specifically recognises the 52kDa parkin protein, when phosphorylated at Ser101.
Parkin is an E3 ubiquitin ligase highly expressed in the brain, which functions in the ubiquitin-proteasome system, together with the E2 ubiquitin conjugating co-enzyme UbcH7. Mutations in the parkin gene are associated with the hereditary neurodegenerative disorder known as autosomal recessive early onset Parkinson disease 2 (PARK2)/autosomal recessive juvenile Parkinson disease (PDJ), characterized by progressive dopaminergic neural cell death. Studies have identified the presence of at least five phosphorylation sites in parkin including Ser101, shown to be phosphorylated by Casein kinase-1 (CK-1), and suggest that phosphorylation of parkin may act to regulate its ubiquitin ligase activity.

For the detection of phosphoproteins, tyrosine phosphatase inhibitors such as 1mM Sodium Orthovanadate should be added to the sample buffer. Milk or other casein-based blocking solutions are not recommended as casein is a phosphoprotein and its use can result in high background.
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
AHP1304 detects a band of approximately 52kDa in HEK293 cell lysates transfected with parkin WT
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
12 months from date of despatch.
Antiserum Preparation
Antisera to human parkin were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG was prepared by affinity chromatography.
