Please find my completed questionnaire. I have also attached the powerpoint slide containing my western images.

I look forward to hearing from you.

Kind regards

1) Abcam product code: ab50358 and ab84955

2) Abcam order reference number or product batch number GR57221-2 and GR64869-2

3) Description of the problem: when running my various lysates for each of the antibodies listed above, the two westerns seem very similar in that the banding pattern seems the same, which triggers my concern over the specificity.

4) Sample preparation:

Lysis buffer: 62.5mMTris – HCl

2% SDS

10% Sucrose

Blocking temperature: as above

6) Primary antibody (If more than one was used, describe in “additional notes”) :

Concentration or dilution: ab50358 1:10,000 and ab84955 1:1000

Diluent buffer: ab50358 1% non fat milk, ab84955 1% BSA

Incubation time: ab50358 overnight, ab84955 1hr

Incubation temperature: ab50358 4C, ab84955 RT

7) Secondary antibody:

Species: Goat

Reacts against: Rabbit

Concentration or dilution: ab50358 1:5000, ab84955 1:1250

Diluent buffer : ab50358 1% non fat milk, ab84955 1% BSA

Incubation time: 1hr

Incubation temperature: RT

Fluorochrome or enzyme conjugate:

8) Washing after primary and secondary antibodies:

Buffer: TBS-T

Number of washes: 3 x 5 minutes

9) Detection method: Amersham ECL plus

10) How many times have you run this staining? 4

Do you obtain the same results every time? Yes

What steps have you altered to try and optimize the use of this antibody? Different primary antibody concentrations, different incubation times and temperatures, different block and diluents buffers, different secondary antibody concentrations

Document attachment: Attaching images of your blot is strongly recommended and can greatly speed up our investigation of your problem.

Thank you for your enquiry regarding ab50358 and ab84955 and for taking the time to provide some useful details of the experiments.

I can confirm that these two antibodies are from two different sources and the immunogen sequences are also different.

After reading through the detailed protocol you kindly forwarded to Abcam, I would like to make the following comments/suggestions:

The protocol looks absolutely fine to me. The band patterns on the WB image look similar but not identical.

Lane 1: it looks like not enough material was loaded,

Lane 2 and 3: there may be protein degradation in the samples,

Lane 5: Major band for Guanylyl Cyclase alpha 1 at 70 kDa whilst for Guanylyl Cyclase beta 1 is at 60 kDa

Although, lysis buffer with proteinase inhibitors were used during sample preparation, protein degradation could still be an issue. In order to be able to prevent any enzymatic degradation, it is important to process the samples as quickly as possible after dissection. Is the human material is from biopsy samples or from postmortem tissues? Have you stored the tissues on ice before and during preparation?

Interestingly, for Guanylyl Cyclase beta 1 two different isoforms have been isolated and reported. You may wish to take a look at this site for further information:


I hope this helps and if I can assist further, please do not hesitate to contact me.

Please could you provide some further details of the protocol used and complete the following form (attached as a word document).

I am particularly interested in the followings:

- Sample preparation,

- Lysis buffer,

- Detection,

- No primary control - only secondary antibody

Thank you for your understanding and co-operation in this matter. I look forward to hearing from you soon and resolving this issue as soon as possible.
