  • Relevance

    Dynorphins are a class of peptides produced by many different populations of neurons, which has some opiate like activity. It is thus classed as an endogenous opioid peptide. The dynorphins, which include dynorphin A, dynorphin B, alpha and beta neoendorphin, and big dynorphin, are all the products of a single gene, 'preprodynorphin'. Dynorphin is produced in many different parts of the brain, including the hypothalamus, the hippocampus and the spinal cord, and has many different physiological actions, depending upon its site of production. Dynorphin is involved in modulating responses to several psychoactive substances, including cocaine. As such, it may help some individuals against addiction. Blocking dynorphin may help alleviate depression.

Thank you for your call yesterday and for your question about these antibodies. I apologize for the delay getting back to you.

We have a general IHC protocol for FFPE sections that includes a section on antigen retrieval-


However, these methods are optimized for slide-mounted tissue, so I have found some other resources that would be more useful for free floation sections-


I've also attached a couple references for free floating antigen retrieval. You should be able to perform this step in a 24-well plate so it will be compatible with your current staining protocol.

I hope this information will be useful, but if you have any further questions or need anything else, please let me know and I'll be happy to help you further.

1. The serum is diluted in PBS, unfortunately we do not have the exact amount that is diluted, however we can estimate the specific antibody concentration to be 0.5-1.0mg/ml. 2. Unfortunately, I have been unsuccessful in locating information to suggest that the immunogen was conjugated to a carrier. 3. We do recommend heat treatment prior to immunostaining of paraffin sections and we have on our website a protocol you might find useful. In the case of Ab11134, heat treatment is essential. Good luck and don't hesitate to contact me for further information.
