Question

Thank you very much for your email.

Here is the answer:

1. As these two species are not tested please run a positive control of human frontal cortex lysate to asses if the antibody is working.

We can not work on human tissue in our lab, since our lab does not qualify to work on human tissues.


2. Are you running the gel under reducing or native conditions?

Yes, we did.


3. Are you checking the transfer? How?

we also ran GAPDH or β-Actin every time when we ran the NPAS4, and the bands was nice, therefore, the transfer would be ok.



4. Please clarify "What dilution buffer was used: 5% milk & 5%BSA"
Are you using 5% milk & 5%BSA at the same time?


No. we generally use 5% milk, since there is no expected bands , we use 5% BSA.


5. What kind of secondary antibody are you using?



1. Peroxidase-conjugated AffiniPure Rabbit Anti-Goat lgG(H+L) (Zb-2306)



2. DyLightTM 800-Labeled Antibody To Goat Lg（H+L）(072-07-13-06)



Please replace the antibody.

Answer

Thank you again for your enquiry


I am sorry that you are having problems with this antibody. Unfortunately, it looks like we are not able to investigate this further, because it may be that the antibody may be working but is not able to detect the protein in an untested species.


Our policy is that we are happy to offer a refund, credit note or free of charge replacement when a product is not working in a successfully tested applications or species (and the product has been purchased in the last 180 days).That means as you are working with a non-tested speciesthat we cannotreplace the antibody.


To help you further with your case, I would like to make the following comments to the answers you kindly provided:


1. There are already prepared human tissue lysates available from different vendors, including us. If you are working with an untested species, it is recommended to run a positive control to asses how well the antibody is working.

2. It is not clear what conditions are used within the gel system. Most of our antibodies are tested and optimised to work under reducing conditions, and we usually state on our datasheet if the gel should be run under non-reducing conditions. I would therefore suggest to run a SDS-PAGE under reducing conditions. Otherwise it may be that the antibody may not be able to detect its target.

3. beta- Actin and GAPDH are internal controls on how well the proteins between 36 and 42 kDa have been transferred, but not a more heavier protein like Npas4. In addition, these two proteins are rather found outside the nucleus, so running a nuclear loading control like TATA binding protein TBP would be more advisable as well. Please check with Ponceau as these twoproteins do notindicate that the transfer is evenly above 42 kDa.


However, to solve this tricky situation, I can offer a discount off a future purchase if you buy ab109984 Anti-Npas4 antibody now, test it again in mouse and/orrat and submit feedback to us in the form of an Abreview. It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback. The discount would be to the value of: 1 free primary antibody.

If you are interested in this offer, please follow these steps:


1. Reply to this e-mail to let me know that you would like to proceed and test ab109984 in mouse and/or rat. I will then send a discount code. This code must be issued before purchasing ab109984 so please wait for my reply before ordering.

2. Purchase ab109984 either by phone, fax, or online (https://www.abcam.com or your distributor).

3. Test it in mouse and/or rat.

4. Let us know the results, positive or negative, using our Abreview system (this will take about 10 minutes and images are great if you have them!). To find out how to submit an Abreview, please visit: https://www.abcam.com/abreviews.

5. After the review is submitted to us, the discount code becomes active. Simply place your new order by phone, fax, or on the web and mention the discount code. The discount can be redeemed for anyprimary antibodyordered and the discount code is valid for 4 months after issue.

Please remember that submission of the Abreview is sufficient for the discount code to become active.

We are always pleased to obtain feedback about our products and any information is greatly appreciated! Even if ab109984 turns out to be unsuitable for mouse and/or rat, you will still receive the discount on your next purchase after your Abreview has been submitted.


Please let me know if you have any questions about this offer and I would be happy to help you further.

Answer

Thank you for taking time to complete our questionnaire. I am sorry to hear that this antibody is not providing satisfactory results.

The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality.


Please be aware that we haven't tested the species you are working with yet, they are only predicted to react due to their sequence homology. Unfortunately, this means that they are not covered by our guaranty.


Having reviewed this case, I would like to offer some suggestions to help optimize the results from ab109984 Anti-Npas4 antibody. I would also appreciate if you can confirm some further details:


1. As these two species are not tested please run a positive control of human frontal cortex lysate to asses if the antibody is working.


2. Are you running the gel under reducing or native conditions?


3. Are you checking the transfer? How?


4. Please clarify "What dilution buffer was used: 5% milk & 5%BSA"
Are you using 5% milk & 5%BSA at the same time?


5. What kind of secondary antibody are you using?



Should the suggestions not improve the results, please do let me know.



I hope this information is helpful, and I thank you for your cooperation.
