Introduction
Phosphorus is essential for multiple and diverse biological functions, including cellular signal transduction, mineral meatbolism, and energy exchange. Elevated levels of serum phosphate may be associated with a higher risk of death and adverse cardiovascular outcomes in people with prior myocardial infarction, and is the subject of large amount of research.
Key Benefits
- Quantitation of phosphate anion in blood, plasma and serum samples.
- Sensitive – can detect upto 200nM phosphate
- Easy to use – Fluorescence (ex/em 535/585nm or Absorbance readout @ 570nm)

Cell Technology’s Phosphate detection kit provides a simple, one-step fluorimetric or colorimetric method for determination of phosphate in serum and plasma samples. The assay is based on an enzyme-coupled reaction that detects inorganic phosphate. The substrate is converted to Hydrogen peroxide in presence of inorganic phosphate in a coupled enzymatic reaction. The Hydrogen Peroxide then reacts with the detection reagent in a 1:1 stoichiometry in presence of Horse Radish Peroxidase to produce the stable fluorescent product.

↓ Horse Radish Peroxidase + Detection Reagent
Fluorescent Product
λmax 570nm. λ ex/em 535/585nm.
Colorimetric assay can be read on a spectrophotometer at 570nm.
Fluorescence is measured at excitation 530nm and emission 585nm.
Fig.1 Phosphate standard curve was generated using fluorimetric detection: excitation 535nm and emission 585nm. Incubation time= 60 minutes at 37oC. Standard curve range 1.5625 µM to 100µM. Graph was plotted using 4PL non-linear regression.
Fig.2 Phosphate standard curve inset: R2 =0.9835. Incubation time=60 minutes at 37oC. Standard curve range 1.5625µM to 25µM. Graph plotted with Linear regression.

患者，双手扶墙，脚尖着地；医生做好消毒,戴上手套，利用放血针（可以利用测血糖的放血针），在委中穴点刺放血，利用拔罐器把瘀血抽出来，直到见到新鲜血液为止。委中穴是解毒大穴。
中医强调治症不治病，虽然身体还有病毒，但是，只要症状能够解除，不影响正常生活和工作，就可以了。
需要强调：医生，一定要做好消毒、保护，防止病毒感染。 另外，可以把艾滋病作为一种疫病，尝试五苓散；五苓散是用来治疗疫病的。
核心抗原由183个或185个氨基酸组成，高度磷酸化，是乙肝病毒核心颗粒的唯一结构蛋白。正由于它存在于Dane颗粒核心结构表面，被表面抗原覆盖，故不易在血循环中检出。核心抗原具有强免疫原性，可诱导很强的体液免疫和细胞免疫，刺激机体产生抗-HBc。
e抗原为可溶性蛋白质，传染性强，游离存在于血液中，虽然很早就被发现，在病理上认为是HBV复制以具有强感染性的一个指标，但其功能尚不清楚。抗-HBe的出现，是预后良好的征象。向左转|向右转
主要是中度以上细胞免疫缺陷包括：CD4+T淋巴细胞耗竭，外周血淋巴细胞显著减少，CD4<200/μl，CD4/CD8<1.0，（正常人为1.25～2.1），迟发型变态反应皮试阴性，有丝分裂原刺激反应低下。NK细胞活性下降。
2.各种致病性感染的病原体检查
如用PCR方法检测相关病原体，恶性肿瘤的组织病理学检查。
3.HIV抗体检测
采用酶联免疫吸附法、明胶颗粒凝集试验、免疫荧光检测法、免疫印迹检测法、放射免疫沉淀法等，其中前三项常用于筛选试验，后二者用于确证试验。
4.PCR技术检测HIV病毒。
流感病毒的基因组包含________基因,其中__________蛋白可作为__________的结构基础.
我不知道第一空如何填,第二空是否应该填"HA蛋白"?第3空是否应该填"突变"?
多谢各位啊!
新年快乐!
万事如意!
1、存在于细胞外环境时，不显复制活性，但保持感染活性，是病毒体或病毒颗粒形式。
2、抗原，是指能够刺激机体产生（特异性）免疫应答，并能与免疫应答产物抗体和致敏淋巴细胞在体外结合，发生免疫效应（特异性反应）的物质
