  • Publication number: 20250002883
    Abstract: The present disclosure relates to a composition for gene editing and a use thereof. According to the present disclosure, an adenine base editor LbABE8e system in which a Cas12a protein variant including one or more mutations and adenine deaminase are fused has altered PAM specificity to achieve a significant genomic single base editing effect on target DNA, and thus expands the range of applicable CRISPR system selection. Accordingly, due to gene editing, it is expected that the adenine base editor LbABE8e system may be widely used in various fields, such as gene therapy, creation of commercial profits with industrial strains with improved productivity, improvement of the quality of public health care through improvement of intestinal microorganisms, and improvement of crops and livestock breeds free from GMO issues.

  • Publication number: 20240386544
    Abstract: A deformation analysis device and a non-destructive analysis method for a secondary battery are capable of accurately diagnosing electrode deformation of the secondary battery using a computed tomography (CT) image. The deformation analysis method for the secondary battery includes performing computed tomography (CT) scanning on each of a first area and a second area of the secondary battery to acquire a first image corresponding to the first area and a second image corresponding to the second area, measuring a first angle from a winding front end to a winding distal end of an electrode of an electrode assembly in the first image and measuring a second angle from the winding front end to the winding distal end of the electrode of the electrode assembly in the second image, and determining that the electrode assembly is deformed if a difference value between the first angle and the second angle is greater than a reference value.
