Question (33651) | Mouse and Rabbit Specific HRP Plus (ABC) Detection IHC Kit (Ready To Use) (ab93697)

Go to datasheet (ab93697)

Question

We have an antibody (a non Abcam one) that is providing a weak signal.
Do you have a fluorescent amplification kit?
Or one with streptavidin that we could then use a fluorescent conjugated anti- streptavidin antibody on?

Answer

Thank you for your enquiry on the phone this morning.

Following on from our discussions, I can recommend to contact the supplier of the antibody that is not providinga strong enough signal in your experiments as it is possible there is a problem with the antibody, or they may be able to provide some more product specific advice. Also, if you colleague that you obtained this from is in a different place and hassent this to you by courier, it may be that it has been damaged by shipping and itmay be better to try a freshvial.

If you would still like to try amplification of the signal, I can confirm that we have the following 2 amplification detection kits which utilize a streptavidin complex:

I suggest you could try the following fluorescent conjugated streptavidin antibodies with this for detection (rather than the HRP). However I am sorry they are not testedfor this type ofapplication:

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contactus.
