Quick Single Pass DNA Sequencing

• plasmid, PCR DNA, and large-insert templates (lambda, BAC, PAC, P1 clones).
• "Load and go" (already cycled) - 2.50 per sample, $160 per plate
• DNA sequencing and cleanup - $7 per sample, $420 per plate.

Direct Colony Sequencing
Instead of purified plasmid DNA, just send us bacterial colonies re-suspended in a small volume of buffer and a sequencing primer (separately or in the same tube). Our skilled professionals will extract and amplify the plasmid DNA directly from the colony, and generate sequencing data with the same exceptional level of quality as our standard sequencing service.

Full Sequence Analysis
ACGT, Inc. offers a Full Sequence Analysis service to confirm the sequences of a clone or detection of mutations or deletions. Our service is comprehensive and results in double-strand sequence data of publication quality. Service consists of the primer walking sequencing method in double-strand or single-strand format. This service includes primer design and synthesis.

High Throughput Sequencing
ACGT, Inc. offers High throughput DNA sequencing in a fully automated lab. We are capable of handling thousands of clones per day using a barcode system to accurately inventory and process DNA samples upon receipt until delivery of final data. Capability to handle up to 3,500 samples per day with numerous ABI 3730XL analyzers. We accept all sample types for preparation of plasmid DNA template: ligation mixtures, transformation supernatants, bacterial cultures, colonies on agar plates, or frozen glycerol stocks.

Intact, high-quality genomic DNA (gDNA) is routinely extracted from blood, saliva, buccal swabs, soft tissues, or plants. We also perform total nuclei acid extractions where gDNA, plasmid DNA and RNA are concomitantly isolated from the same sample such as bacteria. For DNA extraction from plants, the Automated Sample Grinding System (AutoGen) is used to obtain consistent results. Extraction of gDNA from rodent tails or ears is part of our transgenic genotyping service.

DNA Extraction Service Description:

• DNA extraction
• Quantitative analysis by UV spectroscopy and PicoGreen
• Qualitative analysis by UV spectroscopy and agarose gel
• Sample concentration adjustment per customer specifications
• Aliquot of sample into tubes or plates, and shipping to any destination

We offer a complete Genotyping by DNA Sequencing for screening alleles based on nucleotide sequence. Alleles in any organism are detected by PCR amplification of the target gene and DNA sequencing of the resulting PCR product.

DNA sequencing is one of the most definitive methods available for allele identification and genotyping.

ChIP-sequencing (ChIP-Seq) combines chromatin immunoprecipitation (ChIP) and massively parallel sequencing to identify those DNA sequences bound by transcription factors in vivo.

A very common form of ChIP-Seq experiment is the Histone Modification Analysis. Histone compaction of DNA is a well-known epigenetic regulator of gene expression. Post-translational modification of histones, such as histone deacetylation, is another common form of epigenetic control, and is known to be associated with gene silencing. Therefore, evaluation of histone coverage and histone modification status are valuable tools in understanding genome-wide regulation of gene expression.

We offer primarily Targeted Metagenomics services. Targeted metagenomics typically aim at smaller-scale goals, such as the 16S rRNA-based surveys for microbe identification, or acquiring sequence reads with specific protein functions, such as antibiotic resistance genes.

How it works: Total DNA is extracted from the sample, followed by any number of selected PCR reactions. The short PCR products (300 bp maximum size) are purified and are converted to Illumina libraries by the ligation of adapters. Multiplex barcoding is typically used to maximize sample processing efficiency. The libraries are analyzed using long paired-end reads to fully sequence each PCR product in the cluster. The reads are sorted, counted, and non-identical sequences are BLASTed against selected databases for sequence identification.

Epigenetic control is often mediated by methylation of cytosine to 5-methylcytosine (5-mC) in CpG islands. Methylation and/or hydroxymethylation of CpGs near promoters is associated with gene silencing, and has important consequences for gene expression by contributing to the re-modeling of chromatin via recruitment of methyl-CpG-binding domain (MBD) protein complexes and subsequent chromatin modifiers. Disease phenotypes have been shown to arise when these activities are perturbed, resulting in undesired gene expression.

DNA methylation status can be evaluated in two basic ways:

• Whole Genome Bisulfite Conversion.
• Affinity-based isolation of methylated DNA.

High quality plasmid DNA from the Mini to Giga scale is available for many applications including DNA sequencing, transfections, and DNA-mediated antibody production. Resin based methods are used to prepare highly pure plasmid DNA preparations with an option of making these endotoxin-free. Comparable services are available for BAC, lambda, and cosmid DNA.

Extraction of highly pure and intact RNA (total, mRNA, sRNA and miRNA) from a variety of samples including soft tissues (fresh and preserved), blood, saliva, cell cultures, plants, and forensics samples is available whether it from a few samples to large-scale project. Both liquid and resin based purification systems are used to extract the RNA species of interest. Concomitant extraction of genomic DNA and plasmid DNA is possible. The purified RNA is suitable for many downstream applications including cDNA synthesis including library construction, Northern blots and qPCR.

Service Description:

• RNA extraction by liquid or resin based methods
• Quantitative analysis by UV spectroscopy and RiboGreen
• Qualitative analysis by UV spectroscopy and agarose gel

Complete sequencing of transcriptomes has become an important tool in the analysis of gene expression, alternative splice sites, allele specific expression and the discovery and analysis of rare or novel transcripts. Unlike the microarray approach which analyzes the known transcripts contained on the array, with the NGS approach the entire RNA population contained in the sample is sequenced. This provides an unprecedented detail of the transcriptome organization and structure.
