DIG-labeled probes are used for hybridization in Southern, northern, and dot blots, as well as for colony and plaque screening. DIG-labeled hybrids are detected with an anti-DIG-alkaline phosphatase conjugate and the substrates NBT (nitroblue tetrazolium salt) and BCIP (5-bromo-4-chloro-3-indolyl phosphate, toluidinium salt), which give a light-blue precipitate. Sensitivity and specificity: The standard labeling reaction with 1 ?g template will give a yield of 260 ng DIG-labeled DNA after a 1-hour incubation at 37?C, or 780 ng after a 20-hour incubation. The sensitivity of DIG detection depends on the concentration of the DIG-labeled probe in the hybridization reaction, and the duration of the color reaction. Table 1: Sensitivity of DIG detection. 產品簡介: 應用 隨機引物標記用DIG-11-dUTP標記,堿不穩(wěn)定和顏色檢測DIG標記的雜交的DNA探針。使用DIG標記的探針,南,北,斑點印跡雜交,以及菌落和菌斑篩選。 DIG標記的雜交檢測的抗DIG-堿性磷酸酶結合物和底物NBT(氮藍四唑鹽)和BCIP(5 -溴-4 -氯-3 -吲哚基,磷酸t(yī)oluidinium鹽),它給一光藍色沉淀。 產品描述 敏感性和特異性:與1μg模板的標準標記反應將在37℃孵育1小時后,260 ng的DIG標記的DNA得到的收率C,或780納克后孵育20小時。DIG檢測的靈敏度取決于該DIG標記的探針在雜交反應中的濃度和持續(xù)時間的顯色反應。表1:DIG檢測的靈敏度。 1.

This kit offers random-primed labeling of DNA templates with DIG-11-dUTP, alkali-labile, and color detection of the DIG-labeled hybrids. This kit was assembled with convenience in mind, offering a ready-made blocking solution, combined stock solution of NBT/ BCIP, and DIG Easy Hyb granules. The DIG-High Prime mixture includes stabilized Klenow enzyme, nucleotides, primers, and reaction buffer, all in one convenient reagent. Benefits The High Prime method of labeling offers many benefits. Plasmid, cosmid, and lambda phage DNA have all been used as templates. We have achieved equal efficiency when labeling 10 ng to 3 μg of template DNA, which may be linear or supercoiled. Product Description Sensitivity and specificity: The standard assay uses 1 μg of linearized pBR328. It is usual to expect 0.8 μg labeled DNA after 1 hour of labeling, and 2.3 μg labeled DNA after a 20-hour reaction. In a dot-blot hybridization, 0.1 pg of homologous DNA is detectable after a 16-hour color development (probe concentrations at 20 ng/ml). A single-copy human gene (tPA) is detectable in a Southern blot, loading 1 μg of digested placenta DNA. Contents 1. DIG-High Prime, 5x conc., 50 μl 2.
