DBCO-PEG36-TFP ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The hydrophilic PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules. The TFP ester is less susceptible to undergo hydrolysis compared to the NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

PACE Multiplex Master Mix is an advanced and versatile extension of our PACE 2.0 Genotyping Master Mix, formulated for the simultaneous detection of up to four targets in one reaction well. For example, two bi-allelic SNPs, or one reference gene and a further three genes of interest.
PACE Multiplex genotyping assay designs are available from 3CR Bioscience through our free PACE assay design service; once designed, users can purchase assay primers independently or through 3CR Bioscience using our partial or full-assay validation service.
Users will require a plate reader capable of reading FAM, HEX, ATTO 590, ATTO 647N and reference dye ATTO 680 (wavelengths in the PACE Multiplex Master Mix User Guide). PACE Multiplex Master Mix is supplied at 2x concentration for convenience and with or without ATTO 680 reference dye at a range of levels to ensure compatibility with your qPCR machine or reader.
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.
