About the Antibody black filled icon
The classic Y-shaped immunoglobulin is drawn as a stem splitting into two upward arms, with a shorter chain running alongside each arm and small cross bars marking the disulfide bonds at the hinge and along the branches. It stands for immune response, antigen binding and antibody therapy, making it useful for immunology explainers, vaccine and clinical trial slides, biotech product pages, lab report dashboards and medical infographics.
Proportions are symmetrical: rounded tube outlines of even width, arms opening at a wide angle, and three bond markers placed at the hinge and mid-arm to keep the structure readable. It pairs with virus, antigen, cell and molecule icons in the same set. Below 32 px the bond bars merge, so scale up for diagrams.
This is the solid black filled version of the antibody icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
