Abstract: The present invention relates to a method for determining the DNA quality of a biological sample and, more specifically, to a method for determining the DNA quality of a biological sample by performing a quantitative polymerase chain reaction (PCR) using primers capable of amplifying a target gene, a method for preparing the primers used in the method, and a method for standardizing the amount of detected target gene mutation by using the determined DNA quality. The method of the present invention enables objective evaluation of the DNA quality of a biological sample used in gene analysis and the presentation of objective results on the expression ratio of a gene mutation, thereby providing reliable information in the fields of clinical research and companion diagnosis.

Abstract: The present invention relates to a container for centrifugation. The container for centrifugation includes: a main body (100) including a first chamber (110) in which a material to be centrifuged is received, a second chamber (120) in which a suspended material centrifuged from the material in the first chamber (110) is decanted from the first chamber (110) and received and which is positioned on one side of the first chamber (110), and a coupling part (130) formed to surround the first chamber (110) and the outside of the upper end of the second chamber (120); and a cover (200) which covers an upper portion of the main body (100) and forms a fluid communication path (P) of the decanted suspended material between the first chamber (110) and the second chamber (120).

Abstract: A decanting kit for enabling easy separation and extraction for each component comprises: a centrifugal separation container configured to concentrate and separate a sample placed inside for each component according to a density difference during centrifugal separation using a centrifugal separation; a decanting container connected and mounted on an upper part of the centrifugal separation container and configured to decant components separated from the centrifugal separation container while being inclined at a predetermined slope; a floater provided within the centrifugal separation container, configured to move along the longitudinal direction of the centrifugal separation container, and disposed at a boundary of the centrifugally separated components according to a density difference of the centrifugally separated sample for each component; and an insert cover mounted within the centrifugal separation container and configured to limit a movement distance of the floater moving along the longitudinal directi

Abstract: Methods of fabricating semiconductor devices are disclosed. An illustrated example method protects spacers and active areas by performing impurity ion implantation on an oxide layer prior to etching the oxide layer. The illustrated method includes forming a gate on a semiconductor substrate, forming a spacer on a sidewall of the gate, forming an oxide layer over the substrate, forming a mask on the oxide layer to cover a non-salicide area, implanting impurity ions into a portion of the oxide layer which is not covered by the mask, removing the portion of the oxide layer which is implanted with impurity ions, performing salicidation on the substrate, and removing the mask.
