I am a graduate student at University of the Sciences in Philadelphia, I recently ordered and received the ab53027 Anti-CYP2A6 antibody.
I have been using it to try to detect CYP2A6 expression in both Human Liver Microsomes and microsomes I isolated from cell culture.
I have been using it at a 1:1000 dilution - 10uL in 10mL of my blocking buffer, thus far I have had no success detecting the cell's microsomes. I have been able to consistently detect the liver microsomes so I know that my blotting procedure works, the antibody is functional and that I have an appropriate secondary antibody and chemiluminescent stain.
On the product information insert it says to use the antibody at a 1/150 dilution for western blots, this seems quite high. Is it that the antibody is has weak affinity for CYP2A6 and needs to be at such a high concentration?
Also, when I attempted to visit the abcam.com website for more information I found that this particular antibody is no longer available. Is this just a supply issue, or is there a functional reason for this change?
Please advise on what volume of antibody you recommend for me to incubate with my blot, and in what volume of blocking buffer, as well as the duration of incubation i.e. 1 hour, 2 hours, overnight etc.

Thank you for your time.

Please let me know if you need any more clarification on my procedure.

Thank you for contacting us. The recommended dilution of 1:150 is a recommendation which we make to our customers based on our experiments or those of supplier, collaborator or customer input. Although we cannot know exactly why certain products require higher dilutions in different protocols issues of affinity or reaction conditions will play a role. I would recommend using this product at the higher concentration recommended on the datasheet. I would also recommend running a positive control at the same time using the human liver Microsomes and strongly recommend using a loading control such as Beta Actin or GAPDH.They are used to normalize the levels of protein detected by confirming that protein loading is the same across the gel. The expression levels of the loading control should not vary between the different sample lanes. I have included links to these loading controls below. As you have not yet seen expression in your sample cell line I would also recommend a longer incubation, 4C overnight. We currently have a catalog of over 70,000 products. While we do make many of our products in house, we do receive others from outside suppliers. This product has been discontinued by our supplier; we do not know the exact cause for this discontinuation. We do offer a number of other CytochromeP450 2A6 antibodies which we do guarantee to work in western blot on cell lines. Our Rabbit polyclonal antibodies to Cytochrome P450 2A6, AB64890 or AB3570 may best suit your needs. As this product was discontinued shortly after your purchase I can offer you a discount off of anotherCytochrome P450 2A6 antibody should you decide to try one. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
