We are always thrilled to see our products cited in peer-reviewed publications.
This month, we would like to share some publications in which our popular Buccalyse Direct-to-PCR (BEK) kits (sometimes referred to as Buccalyse DNA Release kits) have been used to rapidly extract DNA for applications such as PCR and microarray analysis:
“Advancing human genotyping: The Infinium HTS iSelect Custom microarray panel (Rita) development study” Matute et al (2024)
The objective of this research was to assess the sensitivity, repeatability, reproducibility, accuracy, and precision of an HTS iSelect Custom panel called ‘Rita’, a custom SNP microarray panel developed using Illumina Infinium HTS technology. Designed for high-throughput genotyping, the panel efficiently facilitates the analysis of over 4000 markers associated with health, lifestyle, and forensic factors.
Studies revealed consistent panel performance across different batches and operators, with no significant deviations in call rates or genotyping results. The evaluation confirmed the Rita microarray as a robust, high-throughput genotyping tool, underscoring its potential in genetic research and forensic applications.
Samples for the study were extracted from buccal swabs using the Buccalyse DNA Release Kit. The sensitivity study showed that it is possible to obtain more than a 99 % call rate when working with as little as 0.78 ng of DNA.
The ability to a lower DNA input increases the assay’s utility in forensic laboratories, where casework samples may sometimes contain small amounts of genetic material.
Genes Involved in Susceptibility to Obesity and Emotional Eating Behavior in a Romanian Population Vranceanu et al, (2024)
This study examined the relationship between six obesity-related genes (CLOCK, FTO, GHRL, LEP, LEPR, MC4R) and their impact on measures of obesity and emotional eating behavior in 220 Romanian adults.
Buccal cells were collected from the lateral wall of the oral vestibule and sent for processing in a UK laboratory using the Rapidri Swab kit. DNA was then extracted from the buccal cells using Buccalyse, and genotype analysis was performed using the ABI7900 real-time thermocycler system.
The analysis revealed significant variability in obesity-related phenotypes and emotional eating behaviors across different genotypes. The study provides a foundation for targeted interventions to prevent and reduce obesity and suggests potential strategies for gene expression modulation to mitigate the effects of emotional eating.
“Systemic immunity shapes the oral microbiome and susceptibility to bisphosphonate-associated osteonecrosis of the jaw.” Kaylan et al (2015)
Osteonecrosis of the jaw (ONJ) is a rare but serious adverse drug effect linked to long-term and/or high-dose exposure to nitrogen-bisphosphonates (N-BP). The objective of this investigation was to assess the relationship linking immune function, N-BP exposure, the oral microbiome, and ONJ susceptibility.
To investigate the oral microbiome, Isohelix DNA swabs were used to obtain microbial DNA by running the swab along an area of the outer gumline of subjects. DNA was extracted using the Isohelix Buccalyse DNA extraction kit and stored at −20°C until analysis.
The oral microbiome was characterized by 454 pyrosequencing of the 16S rRNA gene in 93 subjects stratified by N-BP exposure and a history of ONJ.
The oral microbiome was found to be unlikely to cause ONJ. Instead, individuals with bisphosphonate-associated ONJ lacked immune resiliency, which impaired their capacity to respond adequately to the immunological stress of N-BP.
Buccalyse offers researchers a robust, user-friendly tool that consistently delivers reliable results. Its widespread adoption in diverse studies reflects its quality and adaptability, making it an indispensable asset for advancing research in genetics, microbiome studies, and forensic science.
Summary
The above publications feature DNA extracted using the Buccalyse Direct-to-PCR kit being used in a range of molecular biology applications including (but not limited to) genotyping using SNP micorarrays and PCR methods, and 454 pyrosequencing of the 16S rRNA gene for microbiome characterization.
The Buccalyse Direct-to-PCR Kit has been specially formulated to produce high DNA yields from buccal swabs. The kit is a quick and simple one-tube alternative to existing DNA isolation methods when extracting DNA for use in PCR reactions. The yield of DNA from a single buccal swab using Buccalyse is generally around 2 to 4ug from an adult.
