Application Abreviews Notes
IHC-P 1/50 - 1/500.

DyLight® 550 replaces DyLight® 549. The DyLight® 550 excitation is 562nm and the emission is 576nm. DyLight® 550 provides the same orange-to-red fluorescence and photostability as the DyLight® 549 dye. Please refer to the vial in order to check whether the product you received is DyLight® 549 or DyLight® 550 – this information however will have no impact on your experiments. For more information please refer to DyLight® 550.

ICC/IF 1/50 - 1/500.
Flow Cyt 1/50 - 1/200.
WB Use at an assay dependent concentration.

Thank you for contacting Abcam.

I managed to find antibodies against rat GFAP, FOX3, Iba1, and CD68 all raised in different hosts (chicken, rabbit, goat, and mouse, respectively). They each are highly rated by other researchers and have numerous specific published references. The list for these 4 antibodies is given below:
1. GFAP ab4674 (https://www.abcam.com/gfap-antibody-astrocyte-marker-ab4674.html)
2. FOX3 ab104225 (https://www.abcam.com/fox3neun-antibody-ab104225.html)
3. Iba1 ab5076 (https://www.abcam.com/iba1-antibody-ab5076.html)
4. CD68 ab31630 (https://www.abcam.com/cd68-antibody-ed1-ab31630.html)

I also compiled anti-chicken, rabbit, goat, and mouse secondaries with separate emission spectra. We don't have secondaries for these species that weren't raised in any of the 4 species conjugated to a fluorescent protein with a similar spectrum to DAPI. Thus, I think your best bet is to obtain a far-red filter (Cy5), that way you could still stain with DAPI as well. The donkey secondaries that I found with separate emission spectra are listed below:
1. anti-chicken: FITC (https://www.abcam.com/chicken-igy-secondary-antibody-ab63507.html)
2. anti-rabbit: DyLight 594 (Similar spectrum to Texas Red) (https://www.abcam.com/donkey-polyclonal-secondary-antibody-to-rabbit-igg-h-l-dylight-594-pre-adsorbed-ab96921.html)
3. anti-goat: DyLight 650 (Similar spectrum to Cy5) (https://www.abcam.com/donkey-polyclonal-secondary-antibody-to-goat-igg-h-l-dylight-650-pre-adsorbed-ab96938.html)
4. anti-mouse: DyLight 550 (similar spectrum to TRITC) (https://www.abcam.com/donkey-polyclonal-secondary-antibody-to-mouse-igg-h-l-dylight-550-ab96876.html)

The other antibodies you chose (Nogo, heavy neurofilament, caspase 3) seem to be good choices as well as they are tested in formaldehyde fixed, frozen sections via IHC in rat. Below are the antibodies we discussed against those three proteins:
1. anti-Nogo (https://www.abcam.com/nogo-antibody-ab32298.html)
2. anti-heavy neurofilament (https://www.abcam.com/200-kd-neurofilament-heavy-antibody-ab134459.html)
3. anti-caspase 3 (https://www.abcam.com/active-caspase-3-antibody-ab13847.html)

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.
