日本生研甲型/乙型流感酶联免疫诊断试剂盒

1、甲/乙型流感病毒如何划分的？
流感病毒长成这个样子：外面是包膜，里面是核心，表面和里面有一些可供辨识的结构（主要是蛋白/糖蛋白），根据这些在RNA中是否表达来给它们分型和分亚型。RNA可以分成数个片段。
甲乙丙的核心基本结构都是一样的，有核蛋白（对应1个片段）和RNA多聚酶（图中的P蛋白）（对应3个片段）。
甲和乙表面有2种刺突（图中的血凝素和神经氨酸酶）（对应2个片段）
甲和乙的区别在于：甲在包膜上和包膜内有2种膜蛋白（对应2个片段），而乙则是有2种non-structure蛋白（对应2个片段）。所以甲和乙的RNA都是有8个片段。
丙只有1种刺突（血凝素），所以它的RNA有7个片段。
再往下分，还可以分亚型。比如这次的禽流感病毒H7N9，指的是血凝素属于已发现的第7种、神经氨酸酶属于已发现的第9种。
2、抗原检测阴/阳性具有什么含义？抗体检测呢？
免疫系统始终在监视着人体内的状况。病原菌进入人体后，经过免疫系统的处理，那些“可供辨识的结构”们就有可能被识别出来，免疫系统发现这货不是人体正常有的，于是根据这些被识别的标记展开反病原菌行动。被辨识的就是抗原。

Many people think that Pena is a woman's "patent" and has nothing to do with men. actually not. Freckles also have a relatively high morbidity in men. According to statistics, men are suffering from freckles, this absolute number is considerable. Many men are very painful for this, they said: "sad, ah, I am a man, how long also ah!" But, because it is strange genetic freckles, so unless freckle genetically resolved, otherwise No way. In general, as long as men said they have long spots, the basic can be said to be freckles. However, it is a pity that freckle seems to have neglected this male market. Off topic: In fact, men are also very face-oriented, subdivided the market, and occupy the market, for businesses, is also a good choice.

Freckle pathogenic gene found in China:

Known as the "face decimal point" --- freckles sleepy beauty of women and men will have new hope. According to "Health News" reported that the Institute of Dermatology, Anhui Medical University recently has the human body freckles pathogenic genes, locked on chromosome 4 long arm 32-34 zone. This means that freckles can be "smeared" at the genetic level.

This scientific research has been published in the United States published in the field of dermatology, the most authoritative international journal dermatology research magazine. Freckles is an autosomal dominant pigmentation spot. The current clinical use of decolorizing agents and frozen, laser and other methods of treatment, but may form scar or pigmentation. It is reported that freckles gene found in chromosomes is the first time in the world.1, the needle to the large grain of brown small spots, because of its shape, color, such as bird eggs, named freckles.

2, freckles occur in the face, neck, arms and other sun parts, face and more spread in the cheeks and bridge of the nose.

3, the number of freckles uncertain, each non-fusion.

4, there are generally young, more women than men, often accompanied by a family history, no other symptoms.

Freckles are a type of small, spotted, sepals brown or light brown spots that develop on the skin of the face, blotchy. The best part of the hair is the Ministry of the cheek and nasal bridge, but also to the general hair to the entire face or neck, facial appearance is the most common one of the reasons. Most are acquired, some patients are congenital. However, whether innate or acquired, are closely related with genetic factors. In other words, patients with freckles have a certain amount of body mass, and people with this type of body experience freckles under the influence of some external factors (such as sun, dry skin, etc.).
