日本生研甲型/乙型流感酶聯(lián)免疫診斷試劑盒

1、甲/乙型流感病毒如何劃分的？
流感病毒長成這個(gè)樣子：外面是包膜，里面是核心，表面和里面有一些可供辨識(shí)的結(jié)構(gòu)（主要是蛋白/糖蛋白），根據(jù)這些在RNA中是否表達(dá)來給它們分型和分亞型。RNA可以分成數(shù)個(gè)片段。
甲乙丙的核心基本結(jié)構(gòu)都是一樣的，有核蛋白（對(duì)應(yīng)1個(gè)片段）和RNA多聚酶（圖中的P蛋白）（對(duì)應(yīng)3個(gè)片段）。
甲和乙表面有2種刺突（圖中的血凝素和神經(jīng)氨酸酶）（對(duì)應(yīng)2個(gè)片段）
甲和乙的區(qū)別在于：甲在包膜上和包膜內(nèi)有2種膜蛋白（對(duì)應(yīng)2個(gè)片段），而乙則是有2種non-structure蛋白（對(duì)應(yīng)2個(gè)片段）。所以甲和乙的RNA都是有8個(gè)片段。
丙只有1種刺突（血凝素），所以它的RNA有7個(gè)片段。
再往下分，還可以分亞型。比如這次的禽流感病毒H7N9，指的是血凝素屬于已發(fā)現(xiàn)的第7種、神經(jīng)氨酸酶屬于已發(fā)現(xiàn)的第9種。
2、抗原檢測陰/陽性具有什么含義？抗體檢測呢？
免疫系統(tǒng)始終在監(jiān)視著人體內(nèi)的狀況。病原菌進(jìn)入人體后，經(jīng)過免疫系統(tǒng)的處理，那些“可供辨識(shí)的結(jié)構(gòu)”們就有可能被識(shí)別出來，免疫系統(tǒng)發(fā)現(xiàn)這貨不是人體正常有的，于是根據(jù)這些被識(shí)別的標(biāo)記展開反病原菌行動(dòng)。被辨識(shí)的就是抗原。

我司還提供其它進(jìn)口或國產(chǎn)試劑盒：登革熱、瘧疾、流感、A鏈球菌、合胞病毒、腮病毒、乙腦、寨卡、黃熱病、基孔肯雅熱、克錐蟲病、違禁品濫用、肺炎球菌、軍團(tuán)菌、化妝品檢測、食品安全檢測等試劑盒以及日本生研細(xì)菌分型診斷血清、德國SiFin診斷血清、丹麥SSI診斷血清等產(chǎn)品。

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.).
