Real-time PCR is a method that detects the amplification of DNA fragments from PCR reactions as a fluorescent signal for each cycle. This introduces SNP (Single Nucleotide Polymorphism) analysis using the probe method of real-time PCR. Specific base sequences (probes) labeled with a reporter (fluorescent dye) and a quencher (quenching substance) are used to repeat the three steps shown below: 1) to 3). By using different reporters for each base, the SNP base is identified from the fluorescence intensity. Reactions at each step: 1) Thermal denaturation DNA is converted from double-stranded to single-stranded. 2) Annealing and hybridization Primers and probes specifically bind to single-stranded DNA. 3) Extension reaction The probe is degraded by the extension reaction of the primer, releasing the reporter from the quencher, resulting in fluorescence.

SNP (Single Nucleotide Polymorphism) refers to the parts of the DNA sequence that differ by a single nucleotide among individuals. It is believed that SNPs can lead to different characteristics such as physical traits and are also related to drug response.

Additionally, the spatial resolution of the images also varies depending on the diameter of the irradiation beam.

NMR is typically performed using the resonance signals of deuterium (2H or D) nuclei in deuterated solvents for reasons such as ensuring the stability of the magnetic field. However, by using the resonance signals of proton (1H) nuclei, measurements can also be conducted with light solvents (i.e., regular solvents) (No-D measurement method). The effective measurements for the No-D method are as follows: - Measurements to evaluate interactions with light solvents (e.g., degradation studies in light solvents) - Measurements of samples that cannot use deuterated solvents (e.g., samples in the biochemical field such as proteins) - Measurements of samples containing volatile components - Measurements of samples for which no dissolvable deuterated solvents are available.

We created skin tissue samples and evaluated the distribution of biogenic components in freeze-dried samples using TOF-SIMS. Since TOF-SIMS identifies components based on the mass of molecular ions, it does not require labels such as fluorescent substances, allowing for the evaluation of distribution without the influence of labeled materials. The mapping results confirmed that arginine, a natural moisturizing factor (NMF), and cholesterol, which retains moisture as an intercellular lipid, are localized in the stratum corneum. This method is also effective for assessing the permeation state during drug application.
