Question

I will attach few pictures here and in order to get your instruction further. MO3 and Med-2 is samples stained with AB53294/AB7050; and the Isotype-MBP and con-0.125 are stained with Purified Rabbit IgG Isotype /AB7050.

Answer

Thank you for sending the ICC/IF pictures.

The primary antibody stains as it should. The background between the cells can be reduced by exposing the cells for a shorter amount of time when taking an image orchanging the settings on your miscroscope. The images of the cells look very good in my opinion.

What does the image med-2 show: primary + secondary or isotype control + secondary?
This image looks like the primary antibody staining.

The images with the isotype controls (Isotype-MBP and con-0.125) show too muchstainign for a negative control, and do not seem to be working correctly - as the isotype control is a negative control and should not show this staining intensity. How are Isotype-MBP and con-0.125 different from each other?

In order to find out if the problem comes maybe from the secondary or isotype control, I'd suggest to do a no primary control (no primary and only secondary).This control should give youideallyno staining (or just weak non-specific background staining).
Should this control work, thus, give no staining, then that would indicate that there isa problem with the isotype control.

Since the primary antibody is a rabbit monoclonal, thus, using a rabbit monoclonal as isotype control would be recommended.
We carry 2 such isotype controls in our catalog, should you be interested:
ab125938 (https://www.abcam.com/Rabbit-IgG-monoclonal-SP137-isotype-control-ab125938.html)
ab128142 (https://www.abcam.com/Rabbit-IgG-monoclonal-SP137-isotype-control-ab128142.html) prediluted

Further, I'd suggest to use less secondary antibody (1/500 -1/1000) as this would help reducing the background you see between the cells as well.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

ICC with human cell line
isotype crtl: whole cell stained weakly, same as with primary Ab (no difference)
primary Ab: 1/200 1.5 h
block: 1% BSA
2nd: 1/200 (ab7050)
fix: acetone 5-10 min

try no primary crtl, use less secondary (1/500 -1/1000)
send images

Answer

Thank you for contacting us.
I am sorry to hear that one or both of these antibodies seem to not work very well.

As we discussed over the phone, please send me the images with primary antibody as well as isotype control as this will help greatly to understand the problem better.

Also, trying a no primary control, and/or using less secondary (1/500 -1/1000) could help reduce the non-specific background.

I look forward to your reply and to assist you further.
