C57BL/6 mouse splenocytes stained with 17A2 Alexa Fluor® 647 -
Dissected C57/B6 mouse spleen was immersed in 4% paraformaldehyde (PFA) overnight followed by 30% sucrose immersion overnight and frozen in OCT. Frozen section was blocked with 5% FBS and 5% mouse serum for 30 minutes at room temperature. Then the tissue section was stained with 5 µg/mL of anti-mouse CD3 (clone 17A2) Alexa Fluor® 647 (red) and 5 µg/mL of anti-mouse B220 (clone RA3-6B2) Alexa Fluor® 594 (blue) and 5 µg/mL of anti-mouse CD169 (clone 3D6-112) Alexa Fluor® 488 (green) overnight at 4°C. The image was captured by 10X objective. -
Formalin-fixed, 400 micron-thick mouse spleen section was blocked, permeabilized and stained overnight with CD21/35 (CR2/CR1)(clone 7E9) Alexa Fluor® 594 (red), CD169 (Siglec-1) (clone 3D6.112) Alexa Fluor® 488 (green), and CD3 (clone 17A2) Alexa Fluor® 647 (blue) all at 5 µg/mL, optically cleared, then analyzed at 235 µm imaging depth on a confocal microscope. Scale bar: 100 µm. Watch the video. -
Paraformaldehyde-fixed (4%), 500 μm-thick mouse spleen section was processed according to the Ce3DTM Tissue Clearing Kit protocol (cat. no. 427701). The section was costained with anti-mouse CD37 Antibody (clone Duno85) Alexa Fluor® 594 at 5 µg/mL (yellow), and anti-mouse CD3 Antibody (clone 17A2) Alexa Fluor® 647 at 5 µg/mL (magenta). The section was then optically cleared and mounted in a sample chamber. The image was captured with a 10X objective using Zeiss 780 confocal microscope and processed by Imaris image analysis software.

CD3, also known as T3, is a member of the Ig superfamily and primarily expressed on T cells, NK-T cells, and at different levels on thymocytes during T cell differentiation. CD3 is composed of CD3ε, δ, γ and ζ chains. It forms a TCR complex by associating with TCR α/β or γ/δ chains. CD3 plays a critical role in TCR signal transduction, T cell activation, and antigen recognition by binding the peptide/MHC antigen complex

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µL volume. For immunohistochemistry on frozen tissue sections, a concentration range of 2.5 - 5.0 µg/mL is suggested. For 3D immunohistochemistry on formalin-fixed tissues, a concentration of 5.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633 nm / 635 nm.

Related FAQs
- If an antibody clone has been previously successfully used in IBEX in one fluorescent format, will other antibody formats work as well?
-
It’s likely that other fluorophore conjugates to the same antibody clone will also be compatible with IBEX using the same sample fixation procedure. Ultimately a directly conjugated antibody’s utility in fluorescent imaging and IBEX may be specific to the sample and microscope being used in the experiment. Some antibody clone conjugates may perform better than others due to performance differences in non-specific binding, fluorophore brightness, and other biochemical properties unique to that conjugate.
- Will antibodies my lab is already using for fluorescent or chromogenic IHC work in IBEX?
-
Fundamentally, IBEX as a technique that works much in the same way as single antibody panels or single marker IF/IHC. If you’re already successfully using an antibody clone on a sample of interest, it is likely that clone will have utility in IBEX. It is expected some optimization and testing of different antibody fluorophore conjugates will be required to find a suitable format; however, legacy microscopy techniques like chromogenic IHC on fixed or frozen tissue is an excellent place to start looking for useful antibodies.
- Are other fluorophores compatible with IBEX?
-
Over 18 fluorescent formats have been screened for use in IBEX, however, it is likely that other fluorophores are able to be rapidly bleached in IBEX. If a fluorophore format is already suitable for your imaging platform it can be tested for compatibility in IBEX.
- The same antibody works in one tissue type but not another. What is happening?
-
Differences in tissue properties may impact both the ability of an antibody to bind its target specifically and impact the ability of a specific fluorophore conjugate to overcome the background fluorescent signal in a given tissue. Secondary stains, as well as testing multiple fluorescent conjugates of the same clone, may help to troubleshoot challenging targets or tissues. Using a reference control tissue may also give confidence in the specificity of your staining.
- How can I be sure the staining I’m seeing in my tissue is real?
-
In general, best practices for validating an antibody in traditional chromogenic or fluorescent IHC are applicable to IBEX. Please reference the Nature Methods review on antibody based multiplexed imaging for resources on validating antibodies for IBEX.
