SpecificityThis antiserum stains cholinergic neurons in guinea-pig and rabbit. This antiserum is known to react with ChAT of origin guinea-pig, mouse, rat and rabbit.
Species ReactivityGuinea Pig, Mouse, Pig, Rabbit, Rat
Immunogen DescriptionA synthetic peptide (GLFSSYRLPGHTQDTLVAQKSS) as a part of porcine ChAT protein (aa: 167-188) conjugated to KLH
Application DetailsImmunohistochemistry/cytochemistry on 4% PFA or formalin fixed frozen sections; paraffin sections can be more difficult and require more extensive antigen recovery methods. 1:400-1:2000 depending up detection and incubation times ELISA: direct antigen ELISA This antiserum will superbly stain both cell bodies and nerve terminal, and works particularly well in enteric and peripheral neurons. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Reconstitution InstructionsSpin vial briefly before opening. Reconstitute in 100 µL sterile-filtered, ultrapure water. Centrifuge to remove any insoluble material.
Storage InstructionsAfter reconstitution keep aliquots at -20°C for a higher stability, and at 2-8°C with an appropriate antibacterial agent. Glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles.
Batch NumberPlease see item label.
Expiration Date12 months after date of receipt (unopened vial).

Scientific BackgroundThis gene encodes an enzyme which catalyzes the biosynthesis of the neurotransmitter acetylcholine. This gene product is a characteristic feature of cholinergic neurons, and changes in these neurons may explain some of the symptoms of Alzheimer's disease. Polymorphisms in this gene have been associated with Alzheimer's disease and mild cognitive impairment. Mutations in this gene are associated with congenital myasthenic syndrome associated with episodic apnea. Multiple transcript variants encoding different isoforms have been found for this gene, and some of these variants have been shown to encode more than one isoform. [provided by RefSeq, May 2010]
Immunofluorescent staining of rat basal forebrain cholinergic neurons using rabbit anti-ChAT primary and Cy3 secondary antibodies.
Immunohistochemical detection of cholinergic neurons in formalin-fixed floated cryostat sections from the basal forebrain of the rat. Choline acetyltransferase immunoreactivity was detected with the rabbit polyclonal ChAT antiserum (R-043-100; 1:20,000), using the biotinylated secondary antibody-ABC method and nickel-diaminobenzidine chromogen.
