    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 CD21/CD35 (CR2/CR1) Antibody (clone 7E9) Alexa Fluor® 594 at 5 µg/mL (green), and anti-mouse CD8a Antibody (clone C8/144B) Alexa Fluor® 647 at 5 µg/mL (magenta) and counterstained with DAPI (blue). 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.

Description

CD21, also known as CR2 (complement receptor 2) and C3d receptor, binds C3d and iC3b. It is also a receptor of Epstein-Barr virus. CD35, also known as CR1, binds C3b, iC3b, C4b, and iC4b. CD21/CD35 is primarily expressed on B lymphocytes, mast cells, follicular dendritic cells, macrophages, and activated granulocytes. CD21/CD35 forms part of the B-cell antigen receptor complex with CD19 and CD81 and is involved in signal transduction.
