Question


I am using human PBMCs and human bronchoalveolar cells and I am using flow cytometry for analysing the cells.

I bought recently these antibodies:

The primary ab2779 PPAR alpha antibody [3B6/PPAR]

The secondary Ab DyLight® 488 goat anti-mouse IgG (H+L) (ab96879)


Isotype Control: ab91366 Mouse IgG2b [PLPV219]


Now I would like to expand my experiment and analyse PPAR-delta and PPAR-gamma in the same cells and I will use flow cytometry.

My questions:

1- Which PPAR-delta Ab should I use? My suggestion is PPAR-A ab58137.

2- Can I use the same isotype? That is ab91366 Mouse IgG2b [PLPV219]?

3- Can I use the same secondary Ab? That is DyLight® 488 goat anti-mouse IgG (H+L) (ab96879)

4- Which PPAR-gamma Ab should I use? My suggestion is Ab41928.

5- Can I use the same isotype? That is ab91366 Mouse IgG2b [PLPV219]?

6- Can I use the same secondary Ab? That is DyLight® 488 goat anti-mouse IgG (H+L) (ab96879)

Read More
Answer

Thank you for contacting us.
Regarding PPAR-delta ab:
I think ab58137 (www.abcam.com/ab58137) as you suggested would be the best antibody to try as it has been tested in flow cyt and using the same secondary ab (ab96879) would be fine. However you would have to use a mouse IgG1 as a control as the primary antibody (ab58137) has the isotype IgG1. I suggest isotype control antibody, mouse IgG1 [ICIGG1] ab91353 (www.abcam.com/ab91353).
Regarding PPAR-gamma ab, we do not have any antibodies which have been tested in flow cytometry.
However, if you would be willing to test one of these antibodies and providing us with your results, whether positive or negative, I could give you a discount.
Simply follow these easy steps below to apply for our AbTrial Program:
1. Reply to this email, letting us know you are interested in testing this product.
2. Our scientists will email you an inactive personal discount code for the value of the product.

Please let me know if you have any questions about this offer and I would be happy to help you further.
The Terms and Conditions of this offer can be found at: www.abcam.com/abtrial.
If you wish to test the antibody you suggested, ab41928, you could use the same secondary antibody but you would need a mouse IgG2a as a control. I suggest ab91361 as an isotype control (www.abcam.com/ab91361).
I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Hi, I am just starting to use the CD31 antibody to detect the endothelial cells of rabbit vessel sample. We just ordered the Primary Anti-CD31 antibody [JC/70A] (ab9498). I am really new in biology, so please let me ask a stupid question, I guess I can't image the sample with only primary antibody stained, right? What kind of secondary antibody should I use? I find this secondary antibody from related product of the aforesaid primary antibody. Goat polyclonal Secondary Antibody to Mouse IgG - H&L (DyLight® 488), pre-adsorbed (ab96879) Do you think this one is good for my purpose?

Read More
Answer

Thank you for contacting us and asking this question. It does not seem stupid to me at all!

You are correct, you need a secondary antibody that is conjugated to a fluorescent molecule (or an enzyme, followed by the enzyme's substrate to get some color) in order to see where ab9489 is sticking to CD31. The one you picked out, ab96879, is a good choice, assuming you have a microscope that detects fluorescence and has the correct filter for that fluorochrome, DyLight® 488. (It very likely does).

I hope this helps. If you have any other questions, please let us know.

Read More
Answer

Thank you for contacting us.
I am sorry to hear that the antibodies are not working as expected.
As we discussed over the phone, if you please could try the no primary control, this would help us a lot in determining whether the problem comes from the secondary antibody alone, or if there are issues with the primary antibody and isotype control as well.
Please let me know your results.
I look forward to hear back from you and assist you further in resolving his problem.

Question

The customer want ab13579 with Secondary AB .

Application : WB, IHC both FL & Non FL.

In ab96879 = This is not suitable for WB.

Is it possible to use ab96876 or any one that you can suggest ?

Regards

Read More
Answer

Thank you for your enquiry.

ab96876 is a Donkey polyclonal anti mouse IgG secondary, and should therefore detect ab13579TRF2 antibody [4A794]which is a mouse IgG1 primary.

As stated on the datasheet, ab96876 has been tested in IHC-P, ICC/IF, Flow Cyt, and WB.

It is therefore tested and guaranteed for western blot and immunohistochemistry on paraffin embedded sections. I am sorry I am not sure what you mean by IHC both FL - Non FL, could you clarify?

I hope this will be helpful. Please do not hesitate to contact me if you have any further questions.

Question

Hi!
Thank you for your answer.
Now I have fixed my choice on a primary antibody, I need a secondary.
I have always used Alexa-conjugated secondaries so I have no experience of the DyLight and Chromeo-conjugates that you offer. Both exhibit the same fluorescence spectrum and both come at the same price, so it is hard for me to make a choice. Can you help me? What are the main differences between Dylight and Chromeo?
I think the most important parameter for me would be the resistance to photobleaching because I will use a normal epifluorescence and not a confocal microscope so I will have few control over the exposure of the specimen to light.
Best regards.

Answer

Thank you for contacting us.

The fluorochromes which are sold under the brand names Alexa, DyLight or Chromeo are designed to ensure an optimal performance and thus are chemically almost identical. As you may have noticed the advantagesfor these include excellent photostability and bright fluorescence (see also flyer attached). So from this point of view, there is not much of a difference between the DyLights or Chromeos.

Therefore, you may want to make your decision based on other factors:

We offer DyLight conjugated antibodies in the wavelengths 488nm, 550nm, 594nm and 650nm (based on the excitation maxima). These fluorochromes are suitable for most settings. We have Chromeo conjugated antibodies in comparable wavelengths available (488nm, 546nm, 642nm), but also for 494nm and 505nm which are somewhere in between. So if you wish to stain your target in ones of these colours (and your microscope has the correct filter settings), I would recommend the Chromeos.

On the other hand, our DyLight antibody range contains a wide variety of antibody formats, such as antibodies against H&L chain (e.g. ab96879), against the Fc part (e.g. ab98736) or F(ab')2 fragments (e.g. ab98739). Also, within our DyLight antibody range we have a number of secondaries available which have been pre-absorbed against other species to minimise potential cross-reactivity (e.g. ab96879). These advantages might be relevant for you depending on the sample type and species and the primary antibody.

Regarding the resistance to photobleaching, I would slightly prefer the DyLight conjugated antibodies, asaccording to customer feedback they seem to perform excellent. However, this is my opinion only and merelybased on our sales volume for the DyLights; we do not have any further data to confirm this.

I hope this information helps. Please do not hesitate to contact us if you need anything further or if I could help you finding the most suitable secondary for your experiments.
