C57BL/6 splenocytes were stained with CD19 APC/Cyanine7 and CD3ε (clone 500A2) Alexa Fluor® 488 (left) or Syrian Hamster IgG isotype control (right) Alexa Fluor® 488. -
Balb/C mouse frozen spleen tissue slices were fixed with 4% PFA for ten minutes and blocked with 5% FBS for 30 minutes. Then, the tissue was stained with 10 µg/mL of Alexa Fluor® 488 anti-mouse CD3 Antibody (clone 500A2, green), Alexa Fluor® 594 anti-mouse CD11b Antibody (clone M1/70, red) and Alexa Fluor® 647 anti-mouse/human CD45R/B220 Antibody (clone RA3-6B2, blue) overnight at 4°C. Nuclei were counter-stained with DAPI (blue). The image was scanned with a 10X objective and stitched with MetaMorph® software.

CD3ε is a 20 kD transmembrane protein, also known as CD3 or T3. It 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. CD3ε forms a TCR complex by associating with the CD3δ, γ and ζ chains, as well as the 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 5.0 - 10 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.
