外文摘要:NOVELTY - A primer capable of detecting transgenic rice KF6, is new. The detection primer comprises outer and inner upstream primer, and downstream primer. The outer upstream primer KF6-F3 comprises base pair sequence of SEQ ID NO: 1, and outer downstream primer KF6-B3 comprises base pair sequence of SEQ ID NO: 3, and inner upstream primer KF6-FIP comprises base pair sequence of SEQ ID NO: 4, and inner downstream primer KF6-BIP comprises base pair sequence SEQ ID NO: 5.
USE - The primer in kit is useful for detecting transgenic rice KF6 (all claimed).
ADVANTAGE - The primer enables to detect transgenic rice KF6 in a rapid manner with high sensitivity, and specificity, and is easy to use.
DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:
(1) method for detecting transgenic rice KF6 involves subjecting DNA of the sample to loop-mediated isothermal amplification using primer, and detecting presence or absence of transgenic rice KF6 in the amplified product; and
(2) kit for detecting transgenic rice KF6, comprising primer.
TF TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The method involves (a) extracting the sample genomic template, (b) uniformly mixing 40-60 mu M hemin working solution with 1.25 mu M KF6-F3 and KF6-B3 and 10 mu M KF6-FIP and KF6-BIP primer, incubating at 35-45 degrees C for 20-30 minutes, adding 30-40 mM 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) coloring liquid and 50-60 mM hydrogen peroxide, and reading absorbance under UV spectrophotometer at 419 nm, (c) subjecting sample genomic template to loop-mediated isothermal amplification at 60-65 degrees C for 40-60 minutes, and (d) visually determining the reaction color. The method involves adding color reaction mixture comprising 1.4-2 mM deoxynucleotide (dNTP), 3-8 mM magnesium sulfate, 0.6-0.8M betaine, 3.6-10 U Bst DNA polymerase large fragment, 1X Thermopol (RTM: Reaction buffer containing nonionic detergent), and 2 mu l sample genome template, and reacting at 60-65 degrees C for 40-60 minutes. The hemin working solution is prepared by dissolving hemin in a working fluid containing 10 mM sodium phosphate monobasic, 100 mM potassium chloride, 2 mM magnesium chloride and 0.003% Triton X-100 (RTM: t-Octyl phenoxy polyethoxy ethanol). Preferred Kit: The kit further comprises working fluid, hemin, ABTS powder, dimethyl sulfoxide (DMSO) buffer, 30% hydrogen peroxide, 1X Thermopol (RTM: Reaction buffer containing nonionic detergent), dNTP, magnesium sulfate, betaine and Bst DNA polymerase, where the working solution comprises sodium phosphate monobasic, potassium chloride, magnesium chloride and Triton X-100 (RTM: t-Octyl phenoxy polyethoxy ethanol) in a volume ratio of 5:8:1:10.
