Advantages
The D-3-Hydroxybutyric Acid (β-Hydroxybutyrate) Assay Kit is suitable for the specific measurement and analysis of D-hydroxybutyric acid in eggs and egg products and other foods and beverages.
Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.

These kits provide a fast, reliable and convenient method to purify and concentrate high quality, high purity and inhibitor-free cell-free circulating and exosomal RNA using a convenient spin column method. These kits can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used, as heparin can significantly interfere with many downstream applications such as RT-PCR. The purified plasma/serum RNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive reverse transcription qPCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays, and NGS.
Background
Plasma/Serum cell-free circulating RNA or exosomal RNA has the potential to provide biomarkers for certain cancers and disease states. Exosomes are 40 – 150 nm membrane vesicles, which are secreted by most cell types. Exosomes can be found in saliva, blood, urine, amniotic fluid and malignant ascitic fluids, among other biological fluids. Evidence has been accumulating recently that these vesicles act as cellular messengers, conveying information to distant cells and tissues within the body. These exosomes may play a functional role in mediating adaptive immune responses to infectious agents and tumours, tissue repair, neural communication and transfer of pathogenic proteins. For this reason exosomal RNAs may serve as biomarkers for various diseases including cancer. As the RNA molecules encapsulated within exosomes are protected from degradation by RNAses they can be efficiently recovered from biological fluids, such as plasma or serum.
Plasma/Serum RNA Purification Mini Kit
This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 50 µL to 200 µL. The purified plasma/serum RNA is eluted in a flexible final volume of 10 µL to 25 µL.
Plasma/Serum RNA Purification Midi Kit
This utilizes a two column method, and can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 250 µL to 1.5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 µL to 100 µL.
Plasma/Serum RNA Purification Maxi Kit
This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 2 mL to 5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 µL to 100 µL.
