Description
The ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers and templates. The master mix contains a highly stable hot-start Taq polymerase in an optimized buffer with dsDNA specific SYBR green fluorescent dye. Consequently, the ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) features high stability during storage, even at 37°C for weeks. In addition to high sensitivity and signal intensity, the ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) performs a low background/ high specificity qPCR results, as well as a better compatibility with fast PCR program.
With inert smart blue contrast dye, the ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process. The ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) is also compatible with ROX reference dye if ROX is recommended by the manufacturer of the qPCR system. This master mix allows sensitive, precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules.

The sensitivity assay of TQ1200 ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) was examined with serial diluted cDNA from 25 ng to 1.4 fg as templates. The equal intervals of amplification curves also displayed the high precision of TQ1200 in target quantification.
Low Background
The single peak of melting curve displays high specificity of TQ1200 ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX).
The post-amplification melting-curve analysis was examined with 5 ng cDNA as template, abnormally high concentration of primers (400 nM), and TQ1200 ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) or qPCR master mix from brand A as reagents.
High Stability
The overlapped amplification curves and melting curves from different storage conditions display high stability of TQ1200 ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX).
Stability was analyzed via real-time PCR amplification with 1 ng cDNA as template, and TQ1200 ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) stored at -20°C, 4°C, 22°C and 37°C for 30 days as reagents.

若已进入细胞内。则先由巨噬细胞吞噬降解。并形成抗原-MHC复合体传送到表面。被辅助性T淋巴细胞识别和效应T淋巴细胞识别后。效应T淋巴细胞被激活。分解靶细胞。然后再由效应B细胞分泌的抗体进一步消灭病毒。
还有不清楚的么?
荚膜(capsule)是某些细菌在生长繁殖过程中分泌的一层黏液性物质,包围在细胞壁外,通常这种黏液层厚度小于0.2μm,成分是多糖或多肽,只有在营养丰富时或在动物体内,细菌才产生这种半抗原性质的黏液性物质。它具有保护菌体免受巨噬细胞等的捕捉和吞噬,因而具有抗吞噬抗消化、侵袭力强、与致病性关系密切等特点。像肺炎球菌、炭疽杆菌等都有这类荚膜。有些细菌的荚膜层较薄,小于0.2μm,称为微荚。
像链球菌的M蛋白、伤寒杆菌的Vi抗原、大肠杆菌的K抗原等都属于这类微荚膜。
荚膜是某些细菌在细胞壁外包围的一层粘液性物质,一般由糖和多肽组成,是细菌的一种特殊结构。
作用:
①抗吞噬作用:荚膜因其亲水性及其空间占位、屏障作用,可有效抵抗寄主吞噬细胞的吞噬作用。
②黏附作用:荚膜多糖可使细菌彼此间粘连,也可黏附于组织细胞或无生命物体表面,是引起感染的重要因素,具有荚膜的S-型肺炎链球菌毒力强,有助于肺炎链球菌侵染人体;废水生物处理中的细菌荚膜有生物吸附作用,将废水中的有机物、无机物及胶体吸附在细菌体表面上。
③抗有害物质的损伤作用:处于细菌细胞最外层,荚膜犹如盔甲可有效保护菌体免受或少受多种杀菌、抑菌物质的损伤,如溶菌酶、补体等。
④抗干燥作用:荚膜多糖为高度水合分子,含水量在95%以上,可帮助细菌抵抗干燥对生存的威胁。
⑤当缺乏营养时,荚膜可被利用作碳源和能源,有的荚膜还可作氮源。
