Softigel introduces new energy gummies at vitafoods
| By Softigel pbr
Who hasn´t needed a wake-me-up in the morning or hasn´t dragged a tired body to the end of the day? Regardless how we individually spend our day, the intensity of our routine, the sports practice or the stressful of our labor; the common consequence is the high demand and lack of energy.

1.5 Specific dsDNA Quantification UV/VIS-based cDrop™ Method vs Picogreen® Fluorescent Assay
| By Trinean
Precise quantification and normalization of isolated genomic DNA is critical for advanced molecular testing in life science research and molecular diagnostics. UV-Vis based quantification has long been the method of choice, mainly because of its convenience. However, determining the DNA concentration based on the absorbance at 260nm suffers from interference of components such as RNA, proteins and phenols. Alternative methods, such as the PicoGreen® based Quant-iT™ assay, based on fluorescence enhancement upon binding with dsDNA have been developed to address this issue.

1.3 Micro-volume Protein Quantification using the DropSense96 Droplet Plate Reader
| By Trinean
The measurement of protein concentration in aqueous samples is an important assay in biochemistry research and protein production facilities. Spectrophotometric protein quantification assays are commonly used methods to rapidly determine the concentration of a protein. They utilize the direct UV absorbance of the protein at 280nm in combination with its extinction coefficient or an indirect dye-based methods like BCA, Lowry and Bradford assays.

1.2 DropSense96 and its DropPlates, a Versatile Tool for Nucleic Acid and Protein Droplet Quantification
| By Trinean
As the demand for molecular tests increases, automated systems for biomolecule isolation and sample analysis are becoming popular. These facilitate integration of the complete molecular test in a full automatic set-up with liquid robots and bar-coded sample tracking resulting in a significant higher throughput while minimizing tedious manual repetitive tasks. The Trinean technology is a unique combination of the DropSense96 droplet plate reader, the 96well DropPlate microfuidic consumables and the DropQuant analytical software enabling direct quantification of small biomolecule samples in these high throughput, automated workflow.

1.14 Droplet UV/VIS Quantification of Native Proteins in Biopharmaceutical Processing
| By Trinean
Biopharmaceuticals are mainly produced by microbial fermentation or in animal cell cultures. As a consequence, a cascade of procedures including purification and characterization are required throughout the processing chain to obtain the protein at the desired level of purity and potency. Within these processes, quantification of the protein of interest is mandatory at critical steps to maintain confidence in the processing results and fidelity in the end product.

1.20 Quantification of His-tagged IgG antibodies after IMAC Ni-column purification
| By Trinean
Trinean introduces a new cDrop™ application suited for the quantification (OD280) of IgG antibodies and derivatives like Fab fragments during purification by IMAC Ni-columns using imidazole-containing buffers.

Dye-free quantification of Oragene®/saliva DNA extracts using the Trinean DropSense96® Droplet Reader and cDrop™ Spectral Analysis Software
| By Trinean
Saliva samples collected with Oragene® self-collection kits from DNA Genotek offer a non-invasive and proven method for accessing high quality and quantity DNA for genomic testing and analysis. Proper quantification of the extracted DNA is a critical step for most downstream applications. Trinean has developed a specific quantification protocol for DNA from Oragene/saliva samples using the DropSense96® droplet reader and the cDrop™ spectral decomposition software. A comparative analysis using a PicoGreen® fluorescent quantification assay shows a comparable specificity for dsDNA quantification. Since the read-out of 96 samples with the DropSense96 is performed in 5 minutes without any prior mixing or incubation, this technology is a viable alternative to fluorescent quantification assays.

1.7 Quantifying Amplicons in Non-Purified PCR Reactions: Direct Assessment of Product Yield
| By Trinean
The polymerase chain reaction (PCR) is a fundamental tool in molecular biology and clinical testing. Most genetic tests rely upon the power of PCR to enrich specific target-sequences prior to analysis. Analytical methods like sequencing are relatively expensive and labs want to minimize the resources spent on samples that don't meet the requirements of concentration and quality to deliver a reliable result.

1.10 cDrop Protocol for TRIzol RNA Extract Quantification and Content QC
| By Trinean
This cDrop protocol is developed for specific RNA quantification of extracts from a variety of sample origins (human, animal, plant) using extraction kits based on the one-step extraction method using a guanidinium thiocyanate-phenol- chloroform reagent-mix developed by Chomczynski (1). Commercial available variants include the TRIzol® kit (Invitrogen), TRI Reagent® (MRC), RNAzolTM (MRC) and RNA STAT-60TM (Tel-Test).

All-Purpose Protein Sample QC Using a Novel Micro-Volume Platform with Spectral Content Profiling Software
| By Trinean
Accurate total protein quantitation of purified proteins, cell lysates, affinity-column fractions or other complex protein samples is crucial for robust biochemical testing during biopharmaceutical development as well as production. As the presence of chemicals doesn't allow simple A280 protein quantification, more labor-intensive alternatives for quantification are used. Examples are the colorimetric Bradford or BCA assay, which negate to a large extent the presence of contaminants but require multiple steps and show variation depending on the sample composition and time point of measuring within the ongoing reaction.

Precise Nucleic Acid Quantification Using Lab-on-a-chip Spectroscopy and the cDrop Quantification Algorithm
| By Trinean
Precise quantification and quality control of isolated genomic DNA is critical for the success of downstream applications such as next-generation sequencing. Traditionally, two quantification methods have been used routinely: (1) UV/Vis spectroscopy and (2) fluorescence-based assays (i.e. PicoGreen) that utilize DNA intercalating agents.

Sample Processing for the UK Biobank Genotyping Project
| By Trinean
A project was initiated in 2013 to perform SNP genotyping on all UK Biobank participants. The aim of the project (which was to be completed within an 18-24 month timeframe) was to generate high quality genotype data and to make these data available for researchers, via the UK Biobank Showcase system. This poster describes the sample processing workflow, presents a comparison between the two quantification methods used in the project (Trinean DropSense® 96 and PicoGreen) and provides a summary of the genotyping metrics for the (approx.) first 180,000 samples analysed.
