ProtocolSDS

Application

  • For quantitative determination of DNA.

Key Features

  • Sensitive and accurate. Linear detection range 2 ng to 40 ng (100 - 2,000 ng/mL) calf thymus DNA in 96-well plate assay.
  • Simple and high-throughput. The "mix-and-read" procedure involves addition of a single working reagent and reading the fluorescence intensity. Can be readily automated as a high-throughput assay for thousands of samples per day.
  • Low interference. RNA, salt (up to 3M NaCl), detergent (< 0.01%="" sds)="" and="" common="" dna="" extraction="" buffer="" do="" not="" interfere="" in="" the="">

Method

  • FL340/450nm

Samples

  • Plasmid DNA, genomic DNA, cDNA, DNA following polymerase chain reaction, and DNA extracted from gel and other matrices

Species

  • All

Size

  • 250 tests

Detection Limit

  • 100 ng/mL

Shelf Life

  • 12 months

More Details

  • DNA quantitation is a common practice in molecular biology. Very often DNA is available in minute quantities and the traditional UV 260 nm absorbance method requires microgram quantities for reliable results. Accurate determination of DNA concentration, especially when DNA is present at low concentrations, is crucial for reproducible results in sequencing, cloning, transfection and DNA labeling. Simple, direct and automation-ready procedures for measuring DNA concentration are very desirable. BioAssay Systems QuantiFluo™ DNA assay kit is designed to accurately measure nanogram quantities of plasmid DNA, cDNA, DNA following polymerase chain reaction and DNA eluted from gels. The improved method utilizes Hoechst dye that binds specifically with double-stranded DNA. The fluorescence intensity, measured at λex/em = 350/450nm, is directly proportional to the DNA concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.

Can you guarrantee, that your kit enables an accurate estimation of cDNA concentration in RT reaction mixture, where high excess of total RNA is present? Is it a SYBR Green based method?

We are using Hoechst dye based DNA assay. It is very specific for DNA and not RNA. However, as we do not know the RNA content in your sample, we can not judge if it would meet your needs.For more detailed product information and questions, please feel free to Contact Us.

BioAssay Systems的EnzyFluo™ERK磷酸化检测试剂盒的有丝分裂原活化蛋白激酶(MAPK / ERK)途径在细胞增殖,分化和迁移中起关键作用。有丝分裂原刺激最终导致ERK1(T202 / Y204)和ERK2(T185 / Y187)磷酸化。MAPK / ERK级联为癌症治疗的发展提出了许多有趣的药物靶标。BioAssay Systems基于细胞的ELISA可测量全细胞中双重磷酸化的ERK1 / 2,并将信号归一化至总蛋白质含量。这种简单有效的测定方法消除了细胞裂解液制备的需要,可用于研究激酶信号传导和激酶抑制剂对细胞的作用。在该测定中,细胞在96孔板中生长,并用配体或药物处理。然后将细胞固定并在孔中透化。使用荧光ELISA进行ERK1 / 2磷酸化(pERK),然后在每个孔中测量总蛋白。
