עברית: צביעה אימונוהיסטוכימית של תא בעזרת שני נוגדנים:
he:תא מכיל מספר רב של אנטיגנים. התא נחשף לנוגדן ראשוני (באדום) הנקשר לאנטיגן ספציפי (ריבוע סגול), לנוגדן הראשוני נקשר נוגדן שניוני (בירוק) המצומד כימית לhe:אנזים (כחול), האנזים משנה את צבעו של he:סובסטרט וגורם לשקיעתו (כוכב חום).
English: Chromogenic immunohistochemistry staining of a cell with two antibodies: A cell contains a large number of antigens. The cell is exposed to a primary antibody (red) that binds to a specific antigen (purple square). The primary antibody binds a secondary (green) antibody that is chemically coupled to an enzyme (blue). The enzyme changes the color of the substrate to a more pigmented one (brown star).
This chemistry image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Chromogenic immunohistochemistry.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
This chemistry image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
