Question

Thank you for your reply! I hope your holiday was nice and relaxing!
We have already ordered the ab125025 antibody, in part because of your technical responses.
To ensure that we use the antibody properly, is it possible to provide me with the more detailed Western Blot protocol used by your scientists with this antibody? Specifically, the amount and type of blocking and antibody solution (milk or other?), buffer (PBS(T) or TBS(T)), primary antibody incubation time and temperature, secondary incubation time, etc? If you can provide this, that would be great!

Answer

Thank you for contacting us.

As we do not beliefe in "one-fits-all" protocols, and as we do not have any advise on this datasheet, which means that most standard protocols used in our customer labs should be fine. We only give out general advise on e.g. blocking agents when we (or our customers) came along significant problems like when the antibody will work only with 3% BSA or needs 1h incubation only. Please keep in mind that every antibody needs it individual optimization, too.

Nonetheless, for your convenience, I have attached our standard protocol to this email.



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

Question

Inquiry: To whom it may concern, I am interested to know if your anti-ROCK2 rabbit monoclonal antibody (ab125025) was tested for cross-reactivity to ROCK1? On a similar subject, another ROCK2 antibody (ab136442) does not cross-react with ROCK1. Will you please tell me how this was determined? Kindly,

Read More
Answer

Thank you for contacting us and for your patience.

I contacted the laboratory to require more information about how the specificity of ab136442 was tested. I can confirm, that the immunogen sequence of this antibody shows an identity of 75.5% to ROCK1. The specificity was tested performing a dotBlot.

However, I can confirm that the immunogen sequence for ab125025 is not contained in the amino acid sequence of ROCK1 at all. This makes this product very specific for the detection of ROCK2.

For this reason and because the ab125025 is covered by our six month guarantee for more applications (WB, IHC-P, ICC/IF) and species (Mouse, Rat, Human) I would recommend using the ab125025.

If you want to perform IP experiments you might be eligible for the AbTrial with ab125025. You can read more about our AbTrial offer here:

Question

I think I wrote it in the wrong way,
I would like to test an antibody that can detect ROCK (PCP pathway) in westerns and immuno staining. I does not need to inhibit the signalling itself.
Which one can you recommend?

Read More
Answer

Thank you for contacting us.

All the antibodies are well characterized, please choose based on your requirements. e.g polyclonal/ monoclonal, Rabbit/mouse/sheep etc.

The catalogue numbers are:

ab13660, ab45171, ab56661, ab58305, ab125025

ab71598, ab66310, ab10549, ab97592, ab85612

When selecting check the Abreview and choose the antibody which have more Abreview and publications.

Question

I have been using some of antibodies a lot for Immuno-Staining and Western Blotting.
At the moment I am interested in looking at a functional ROCK antibody and its regulation during PCP / Wnt signalling.
Is there an antibody in your product catalogue you can recommend ?
Thanks for your help,
Constanze

Answer

Thank you for contacting us.

We unfortunately do not have anti ROCK antibodies available that can be used for functional assays e.g. activation or inhibition of ROCK. I would suggest searching the similar antibody clone in publications. We have 6-7 monoclonal antibodies in catalogue however we do not know whether these are being used in any functional assay. I am sorry we are unable to help with this particular ab.
