Common Challenges and Practical Solutions in the Pursuit of High-Performance Assays
Are you attending the Plant and Animal Genome (PAG) Conference XXIV in San Diego January 9-13? Bioline is exhibiting, as well as hosting an industry workshop this year at PAG, and invites you to join.
On Monday, January 11 from 6:10 – 8:20 pm Bioline is hosting an industry workshop, ‘Common Challenges and Practical Solutions in the Pursuit of High-Performance Assays.’ Both Rory O’Neill, PhD, and Ben Jackson will be giving an informative presentation describing the Application of Design of Experiments (DoE)m methodology to the development of high-performance buffers. A question and answer session will follow with light refreshments and beverages. The workshop will be hosted in the Royal Palm Salon 3-4 at the Town and Country Hotel.
Bioline will be exhibiting at PAG from Sunday, January 10 – Tuesday, January 12 in booth 432. Visit the booth and learn how Bioline can assist you from experimental design, to sample isolation, to your PCR/qPCR and analysis needs. Of particular interest to PAG attendees may be:
- JetSeq DNA Library Prepartation: NGS DNA Library Preparation with faster results, a simpler protocol and increased yield
- Custom PCR/qPCR Solutions: for real-time PCR, end-point PCR and nucleotide chemistry
- SensiFAST Genotyping Kits: for high-throughput genotyping
Be sure to visit Bioline at booth 432 while at PAG. We look forward to seeing you!

American Society of Human Genetics 2012 Annual Meeting
Bioline was once again an exhibitor (#Booth 1324-1326) at the American Society of Human Genetics (ASHG) annual meeting held in San Francisco in November. The largest human genetics meeting in the world, ASHG 2012 attracted over 7000 delegates to discuss the very latest advances in basic and clinical research.
Sessions included topics such as comparative epigenomics, early exome sequencing in complex traits, large-scale identification of regulators of translation and integrated genetic and functional studies of disease-causing variants.
Bioline USA at ASHG 2012
Bioline unveiled its new format exhibition stand at the conference, where our representatives met with scientists and discussed solutions to their molecular biology challenges. Bioline PCR Specialist, Dr. Sven Bocklandt gave a series of well received and thought-provoking talks on some of our latest products, including SensiFAST™, MyFi™ and MyTaq™ DNA polymerases. Exciting results from both published papers and some unpublished experiments from the Bioline scientific community were presented, including results from the Bioline PCR Challenge.
In keeping with ASHG 2012, this month's Bioline scholar is dedicated to Human Genetics. We are pleased to highlight a selection of recent papers featuring Bioline products, perfectly suited for both small- and large-scale genetic and genomic studies in humans.
Mutations in MTM1 (myotubularin 1) cause X-linked myotubular myopathy that affects 1 in 50,000 males. In neonates or infants, movement and breathing are severely affected. The authors developed a MTM1-specific database of genetic variants, with 474 identified mutations from 472 patients. Next-Gen sequencing (Illumina HiSeq) and cDNA analysis revealed the presence of a novel MTM1/MAMLD1 fusion transcript in one case.

Children with X-linked retinitis pigmentosa (XLRP) often go blind by the second decade of life. A severe form of XLRP, RP23, was previously mapped to a 10.71Mb interval on Xp22.31-22.13, containing 62 genes. Using targeted NGS (Illumina), the authors identified a deep intronic mutation in OFD1 as the most likely cause of RP23. Insertion of a cryptic exon produces an aberrant transcript and reduced levels of correctly spliced transcript. This is predicted to result in a severely truncated protein and decreased levels of normal protein.

The genetic basis for susceptibility to malaria in a Vietnamese population was investigated by SNP genotyping by researchers from Oxford University and the MalariaGen consortium. Data from 65 SNPs in 42 malarial candidate genes in 956 severe malaria cases and 2350 controls from Vietnam was reported. Variants in six genes (ICAM1, IL1A, IL17RC, IL13, LTA and TNF) encoding adhesion and pro-inflammatory molecules were associated with severe malaria.

Facioscapulohumeral muscular dystrophy (FSHD), characterized by muscle weakness and wasting, is associated with a shortened telomeric chr 4q35 due to deletions of the D4Z4 tandem repeat (FSHD1) or DNA methylation changes of D4Z4 (FSHD2). Using exome sequencing (Illumina NGS) the authors identified two known pathogenic mutations in CAPN3, indicating a case of limb-girdle muscular dystrophy type 2A (LGMD2A) rather than FSHD2. The authors conclude that ‘diagnosis by sequencing’ of FSHD may be more commonly adopted in clinical genetics laboratories around the world.

An arrayed human genomic library comprising 115,000 PAC clones was constructed. Functional studies with a p53-containing PAC clone in p53-null human osteosarcoma cells showed the utility of individual library members in human cell culture models. The library can be used to validate candidate genes identified by GWAS and for gene therapy in different recessive disorders.

Charcot-Marie-Tooth disease (CMT) is an inherited disorder of peripheral nerve dysfunction resulting in numbness and weakness. Mutations in four genes encoding an aminoacyl-tRNA synthetase (ARS) have been associated with CMT. This study from the University of Michigan found that the p.Arg329 AARS mutation is a recurrent, loss-of-function mutation that arises due to methylation-mediated deamination of a CpG dinucleotide.
