| 설명 | 혈장이나 체액 속에 존재하며 입자, 특히 세포나 미생물과 결합하여 강한 탐식성을 가진 큰포식세포 또는 과립 백혈구에 의한 포식작용을 쉽게 하여 주는 인자를 말한다. 포식세포 표면에는 항체의 Fc 분절수용체 또는 보체의 활성화 분절 C3b의 수용체가 존재하므로, ① 항체(특히 IgG와 IgM), ② C3b, ③ 항체도 보체도 아닌 것 등이 옵소닌으로서 작용한다. 1903년 라이츠 및 더글러스에 의해 발견되어 자연면역의 중요한 요소라고 생각되었다. 이 물질의 구조는 아직 알려지지 않았지만, 56℃에서 30분간 가열하면 작용이 없어지고 보체를 첨가하면 활성화된다. 특이성은 적고 여러 가지 세균에 작용한다. 백혈구-세균-혈청을 혼합하여 도말표본을 만들어 백혈구에 먹힌 세균 수를 세어 보면 옵소닌의 세기를 알 수 있다(옵소닌지수). |

| thermolabile opsonin | That normally present in the blood, i.e., without stimulation by a known, specific antigen such as certain complement components; it is relatively thermolabile and reacts with various organisms. Synonym: common opsonin, thermolabile opsonin. Specific opsonin, antibodies formed in response to stimulation by a specific antigen, either as a result of an attack of a disease, or injections with a suitably prepared suspension of the specific microorganism. Synonym: immune opsonin, thermostable opsonin. (05 Mar 2000) |

| opsonin | <protein> Substance that binds to the surface of a particle and enhances the uptake of the particle by a phagocyte. Probably the most important in mammals derive from complement (C3b or C3bi) or immunoglobulins which are bound through the Fc receptor). (18 Nov 1997) |
| thermostable opsonin | specific opsonin |
| thermostable opsonin test | A test for opsonic activity of antibody in the absence of effect of heat-labile complement. (05 Mar 2000) |
