Our Abpromise guarantee covers the use of ab68779 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 - 10 µg/ml. This antibody has been tested in Western blot against the recombinant peptide used as an immunogen. We have no data on detection of endogenous protein.
IHC-P Use a concentration of 1 - 10 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
IHC-Fr Use a concentration of 1 - 10 µg/ml.
ICC/IF Use a concentration of 1 µg/ml.


  • FunctionCatalyzes the reversible synthesis of acetylcholine (ACh) from acetyl CoA and choline at cholinergic synapses.
  • Involvement in diseaseDefects in CHAT are the cause of congenital myasthenic syndrome with episodic apnea (CMSEA) [MIM:254210]; formerly known as familial infantile myasthenia gravis 2 (FIMG2). CMSEA is an autosomal recessive congenital myasthenic syndrome. Patients have myasthenic symptoms since birth or early infancy, negative tests for anti-AChR antibodies, and abrupt episodic crises with increased weakness, bulbar paralysis, and apnea precipitated by undue exertion, fever, or excitement.
  • Sequence similaritiesBelongs to the carnitine/choline acetyltransferase family.

Anti-Choline Acetyltransferase antibody images

  • ICC/IF image of ab68779 stained PC12 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab68779, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) ab150077) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI (ab104139) was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

I recommend starting with a dilution of 10ug/ml, which is 1/100 if using the stock 1mg/ml antibody solution you receive, or 1/50 if you dilute what you receive with glycerol to a final percentage of 50% glycerol. You may want to test a series of diluti...

Thanks a lot for clarifying.
As a negative control for your IHC assay, I would recommend using an isotype control, an antibody from the same species and isotype as the primary with does not target any specific protein.
I conducted a search fo...

Thank you for your enquiry.

As glycerol is a cryoprotectant, if the antibody has been frozen for a few months without it, it may regrettablyalready be damaged.

However, I would suggest to try one aliquot of each antibody in an exp...

Thank you for your reply.

When you add glycerol to a final volume of 50%, it means that half of the total finalvolume should be antibody and half of the volume should be glycerol. Therefore, if the antibody is 100ul, you should add 100u...
