About the Antibody black outline 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 black outline version of the antibody icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
