Thank you for contacting us and you interest in our products.

There are a few differences between the two pairs of antibodies you have identified. A few of these include the purification used (affitiny vs IgG fraction) as well as the ratio of conjugation. The ab6788 and ab6720 is estimated to have a conjugation ratio of 10-20 per IgG molecule whilst ab97049 and ab97021 have a ratio of 1:4.

I am not familiar with the amplification technique you intend to use and cannot therefore anticipate how these differences may alter the results.

If you could share a more detailed description of the procedure I may be able to advise in more detail.

I hope this information has been of help. If you have any further questions, please do not hesitate to contact us again.

Thank you so much for your call today and for letting us know about the trouble with the staining.

As we discussed, I'm sending a free of charge DAB avidin-biotin complex staining kit, ab64261, which should arrive on Monday on the order ***.

Please keep me updated about the results after using the kit, and let me know if you have any questions or if there is anything else that we can do for you.

Have a wonderful weekend!

Thank you for contacting Abcam.

As with most antibodies the dilution that works best for you depends on multiple varaibles and so you should do some titrations to find the best for you, but I placed a good starting point next to each.

1-ab33923 - IHC-P: 1/50
2-ab6668 - ICC/IF: 1/1000, WB: 1/2000, ELISA: 1/50000
3-ab6822 - WB: 1/2000, ELISA: 1/200000, ICC/IF: 1/1000, IHC-P:1/100
4-ab7481 -10%
5-ab97049 - IHC-P: 1/500, ICC/IF: 1/200, ELISA: 1/20000, WB: 1/10000.

Ifthere is anythingelse I can help you with, or ifyou would like a starting concentration for an application that I did not list about, then please let me know.

Thank you for your email! The best way to figure out dilutions and number of tests is to look at the datasheet. In most cases we will have a recommended dilution for each application, and will also include the concentration of the product along with the amount of product in the vial. Using these pieces of information, you can get the number of experiments that you will be able to do with that product. In order to give you the number of tests, I will need to know what application you are looking to use the antibodies in. The calculator at the following link may help you: https://www.msu.edu/~nixonjos/more/dilution.html?stock=1&needed=0.0001&volume=1&total=0.1 To get the number of tests, you can divide the final result ("total stock solution to use") by the amount included in the tube. I hope this helps. If you have any further questions, please do not hesitat
