  • 特異性

    By immunoelectrophoresis and ELISA this antibody reacts specifically with rat IgG and with light chains common to other rat immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. Less than 1% cross reactivity to bovine, chicken, goat, horse, human, mouse, rabbit and sheep IgG was detected. This antibody may cross react with IgG from other species.

Question

Thank you for the detailed reply.

I met the customer and she explained me that she performed the parallel stainingof the same cells transfected with the same plasmid at the same time. The staining was performed with the same 1ary ab and the only difference was the secondary ab: AlexaFluor in comparison to Dylight.

The staining with Alexa succeeded whereas Dylight showed non specific staining.

Please advise.

Thanks in advance fro your reply.

Answer

Thank you for your message and for your efforts and time with this customer.

I am sorry to hear the suggestions made have not improved the results on this occasion. I appreciate the time you have spent on these experiments, and would like to offer a refund or credit note in compensation (providing the product has been purchased in the last 6 months). In order to arrange this, I would appreciate if you could confirm the order number and date of purchase as previously requested.

Thank you for your continued cooperation. I look forward to hearing from you with details of how you would like to proceed.

Question

Thank you for the reply.

Please read below customer's details:

1. Yes, this is not specific staining.

I used primary Rat-anti-HA Ab (Roche 12075900)

2. i. C33A were stained in Image004_ch00

primary keratinocytes were stained in Image 6-1_ch00

ii. The target is transfected E6AP-HA protein. Dilution of primary Ab is 1:150

iii. Incubation time is 2h in room temperature for the primary antibody

iv. Antibody is week and non specific.

3. I didn't use this secondary antibody with other primary antibodies.

I will include a no primary control and I can try to lower concentration of the secondary antibody, but I don't believe that it will improve the results since the antibody is very week and since I try to detect the transfected protein, I expect to see only several cells stained (like in Images 005 and 014) and not the whole field weekly stained.

Please advise.

Thank you for the assistance.
Best Regards,

Answer

Thank you for kindly providing this further information.

I appreciate your cooperation and understand your concerns. It is regrettable the results have not been successful.

Reviewing the details, I would like to provide some suggestions and considerations that I hope will help solve the problem, and also request some further information which will help with our investigations.

1. There are inherent difficulties with antibody detection of recombinant tagged proteins that I can recommend considering. This may be a biological artifact rather than a problem with the antibody. Could you confirm that the protein transfected is full length and includes the full immunogen sequence for the primary antibody?

Also, if the recombinant E6AP-HA protein is tagged, it is possible that the tag is preventing access to the antibody. Could you confirm at which region of the protein the tag has been placed?

2. Could you confirm how the stability of transfection has been assessed?

3. What type of optimization has been tried with the primary antibodies? For example, has a dilution range been tried? As previously discussed, overnight incubation at 4oC can often provide more efficient and specific staining.

4. I can recommend that due to the points described above, it is important to include an endogenous positive control sample for the primary antibodies.

5. I can suggest it would be important to try the secondary antibody with another primary antibody (detecting an endogenous, not recombinant protein) to help assess how well this is working.

Or, has a different secondary antibody been tried on the same samples with the same primary antibodies?

6. We recommend wash steps are 4 times for 5 minutes at each appropriate wash step if this has not already been tried.

I will be pleased to provide a free of charge replacement or credit note if the antibody is not working with the suggestions provided and an endogenous positive control.

Thank you for your time. I look forward to hearing from you with the requested information and hope we can resolve this case as soon as possible.
