【什么是質(zhì)控品】

1. 質(zhì)控品的來源： 
  質(zhì)控品的來源同校準(zhǔn)品大致相同，廠商可能會更具自己的要求添加了很多物質(zhì)，此時有些物質(zhì)的添加量常常達(dá)到病理狀態(tài)的高濃度，在應(yīng)用于某一項目時，對這個項目來說基質(zhì)效應(yīng)將更大。

2. 定值方法： 
  有些廠商會給自己的標(biāo)準(zhǔn)品定一個定值范圍，這個定值范圍是由廠商聯(lián)合幾家使用同樣檢測系統(tǒng)的臨床用戶，僅多次測定得出的均值。此時如果將該質(zhì)控品應(yīng)用于另一個檢測系統(tǒng)，由于方法學(xué)的不同，可能得出同廠商給出值有較大差異的值。此時不能認(rèn)為該檢測系統(tǒng)的準(zhǔn)確度不佳。此時需要強調(diào)的是檢測系統(tǒng)都是用來測定新鮮血清的，不是用來測定質(zhì)控品或其他物質(zhì)的。檢測系統(tǒng)只有在檢測新鮮血清是得出的結(jié)果才具有溯源性。不同檢測系統(tǒng)之間只有在檢測新鮮血清時才具可比性。

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。

提出細(xì)胞系選擇學(xué)說。該學(xué)說闡明了抗體產(chǎn)生的機制，并對諸如抗原識別、免疫記憶及自身耐受與自身免疫等許多重要免疫生物學(xué)現(xiàn)象作了解釋，大大促進(jìn)了現(xiàn)代免疫學(xué)的發(fā)展。該學(xué)說基本觀點為① 認(rèn)為機體內(nèi)存在識別不同抗原的多種細(xì)胞系，每一細(xì)胞系的細(xì)胞表面表達(dá)識別相應(yīng)抗原的同一受體；② 抗原進(jìn)入機體后，選擇性地與具有相應(yīng)受體細(xì)胞系的細(xì)胞作用，使之活化、增殖、分化成效應(yīng)細(xì)胞或記憶細(xì)胞；③ 胚胎期針對自身抗原的免疫細(xì)胞與自身抗原接觸后可被破壞、排除或處于抑制狀態(tài)；④ 免疫細(xì)胞可突變形成與自身抗原反應(yīng)的細(xì)胞系，導(dǎo)致自身免疫病。四、免疫學(xué)技術(shù)的發(fā)展在此期間，免疫學(xué)技術(shù)也得到快速發(fā)展，建立了間接凝集反應(yīng)和免疫標(biāo)記技術(shù)，進(jìn)一步促進(jìn)了免疫學(xué)基礎(chǔ)理論的研究和應(yīng)用?，F(xiàn)代時期現(xiàn)代免疫學(xué)時期指  世紀(jì)  年代至今的時期。在這一時期，確認(rèn)了淋巴細(xì)胞系在免疫反應(yīng)中的地位，闡明了免疫球蛋白的分子結(jié)構(gòu)與功能，對免疫系統(tǒng)特別是細(xì)胞因子、粘附分子等進(jìn)行了大量研究，并從分子水平對免疫球蛋白的多樣性、類別轉(zhuǎn)化等進(jìn)行了有益的探討，在許多方面取得了突破性成就。一、免疫系統(tǒng)的研究 年 Click 發(fā)現(xiàn)摘除雞法氏囊，可引起抗體產(chǎn)生缺陷。認(rèn)為法氏囊是抗體產(chǎn)生細(xì)胞存在的主要場所，并將產(chǎn)生抗體的細(xì)胞稱為 B 細(xì)胞。
Proposed cell line selection theory. The doctrine elucidates the mechanism of antibody production and explains many important immunobiological phenomena such as antigen recognition, immune memory, autotolerance, and autoimmunity, which greatly promotes the development of modern immunology. The basic idea of ??the doctrine is 1 that there are multiple cell lines in the body that recognize different antigens. The cell surface of each cell line expresses the same receptor that recognizes the corresponding antigen; 2 antigens enter the body, selectively and have corresponding receptor cells The cells of the line are allowed to activate, proliferate, and differentiate into effector cells or memory cells; 3 immune cells against the autoantigen in the embryonic stage can be destroyed, eliminated, or inhibited upon contact with the autoantigen; 4 the immune cells can be mutated and formed. Autoantigen-responsive cell lines lead to autoimmune diseases. Fourth, the development of immunology technology During this period, immunology technology has also been rapid development, the establishment of indirect agglutination and immune labeling technology, further promote the basic theory of immunology research and application. The modern period of modern immunology refers to the period from the present century to the present. During this period, the status of the lymphocyte line in the immune response was confirmed, the molecular structure and function of the immunoglobulin were elucidated, and a large number of studies on the immune system, in particular, cytokines, adhesion molecules, etc., were carried out at the molecular level. The diversity of immunoglobulins and class transformations have been usefully explored and breakthroughs have been achieved in many areas. First, the immune system research Click Click to find chicken bursa removed, can cause antibody defects. The bursal is considered to be the main site for the presence of antibody-producing cells, and the antibody-producing cells are referred to as B cells.
