The Lactulose Assay Kit is suitable for the specific, rapid and sensitive measurement and analysis of lactulose in milk and milk-based samples. Reagents included in this kit may also be prepared for use in the procedure described by ISO Method 11285:2004.

Overview

• Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
• ​Versatile sample input ranges
• Isolate all sizes of free-circulating RNA, including microRNA
• The purified exosomal RNA is free from any circulating RNA-binding proteins
• No phenol extractions, Proteinase K treatment, nor carrier RNA
• No time-consuming ultracentrifugation, filtration nor special syringes are required
• No precipitation reagents, nor overnight incubation required
• Concentrate isolated exosomal RNA and are free-circulating RNA into a flexible elution volume ranging from 50 µL to 100 µL
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

These kits provide a fast, reliable and convenient method to sequentially isolate and concentrate exosomal RNA as well as Free-Circulating RNA from different plasma/serum sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA as well as all sizes of the free-circulating protein-bound RNA, including microRNA. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, these kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.

Important Note
This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma 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.

Description

Specifications

SRY (Sex Determining Region Y)-Box 10 (SOX-10), also known as transcription factor SOX-10, is a nuclear transcription factor that acts in regulation of embryonic development and in the specification and differentiation of cells of melanocytic lineage. SOX-10 is diffusely expressed in neurofibromas and schwannomas, and mutations in the SOX-10 gene are linked to Waardenburg-Shah and Waardenburg-Hirschsprung disease. Anti-SOX-10 has been shown to be sensitive for conventional, spindled, and desmoplastic melanoma, and has been used to detect metastatic melanoma and nodal capsular nevus in sentinel lymph nodes.

N-(Acid-PEG2)-N-bis(PEG2-propargyl) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.

Bring your assay kits to the next level with freeze-dried PCR beads.

LyoBeads are ready-to-use, freeze-dried master mixes in shape of a small ball or spheres.

LyoBeads contain: DNA polymerase(s), reaction buffer, dNTPs and primers and probes. They are rehydrated within seconds in any aqueous solutions, which  makes reaction setup very simple. Only a biological sample has to be added.

Storage: LyoBeads are shipped and stored simply at room-temperature. This provides a more cost efficient and ecological distribution compared to other master mixes.

LyoBeads can be pre-dispensed in PCR-strips, PCR-plates, cartridges etc.

Example performance data can be downloaded here.
