Product Highlights
- Robust: optimized proprietary buffer system designed for overcoming common PCR inhibitors in crude lysate or unprocessed blood, tissue and plant samples
- Specific: antibody-mediated hot-start DNA polymerase minimizes non-specific amplification for improved assay sensitivity and reliability
- Sensitive: reliable quantification of low abundance targets and scarce samples
- Reproducible: consistent results between technical replicates for increased confidence in results
- Fast: delivers reproducible, multiplex accurate assay results in as little as 30 minutes
Product Description
SensiFAST™ Direct Probe SuperMix is a combination of the latest advances in buffer chemistry and PCR enhancers and stabilizers, together with an antibody-mediated hot-start polymerase, dNTPs and MgCl2. It has been designed for highly reproducible, accurate assay results in the presence of inhibitors, making it ideal for direct amplification directly from the most challenging samples.
The advanced buffer chemistry and enhancers has been developed for fast qPCR and is designed for superior sensitivity and specificity with probe‑detection technology, including TaqMan®, Scorpions® and molecular beacon probes, making SensiFAST Direct Probe SuperMix perfect for multiplexing, allowing more samples to be run in a day with the highest confidence, ideal for high‑throughput assays.
Applications
- Gene expression analysis
- Viral and bacterial detection
- GMO testing
- SNP genotyping

短截就是把枝条剪短,主要作用是促使其抽生新梢,增加分枝数目,以保证树势健状和正常结果。短截常用于骨干枝组修剪,结果枝组修剪,和树体局部更新复状。
短截按其长度可分为:
① 中短截:在一年生枝的中部短截,剪后萌发的顶端枝条,长势强,下部枝条长势弱。
② 重短截:剪去一年生枝的2/3。剪后萌发出的枝条较强状,一般用于主侧枝延长头修剪。
③ 重剪:剪去一年生枝的3/4-4/5,剪后萌发出的枝条长势强状,常用于发育枝作延长枝头和徒长果枝,中果枝的修剪。
④极重短截:剪去一年生枝的4/5以上,萌发后的枝条中庸偏状,常用于将发育枝和徒长枝培养结果枝组。
⑤留基部2芽剪:剪后萌发枝条较旺盛,常用于预备枝的修剪。对于幼龄树,树势较旺,以培养良好而牢固的树形结构,提早结果为主要目的,以轻短截,少疏间为主,从始果期到盛果期,主要使桃树多结果,并形成好的树形。
试剂里面含有的是病毒的抗原,现在基本都是人工合成或提取的,跟病毒完全是两回事
