Detail
Overview
Perforated heat sealing film which is optically clear. This seal has 3 mm slits for gas transfer; is suitable for insect studies and seed storage too.
Heat sealing is a quick and cost effective method of plate sealing
Our ClearASeal Perf Heat Seal is based on our ClearASeal Peel, with the addition of 3 mm slits across the width of the seal
These slits render the seal gas permeable, whilst retaining evaporation to a minimum, compared to the use of lids
The ClearASeal Perf Heat Seal is compatible with polypropylene, polyethylene, polystyrene and cyclic olefin copolymer (COC) plates
The Seal has a wide seal integrity temperature range, from -80 °C to 110 °C
It can be used for insect and seed storage, as it enables gas exchange, whilst providing an inert surface with no adhesive to interfere with the well contents
This seal is available as sheets, for use with manual and semi-automated sealers, such as our HeatASeal 500 Sealing Machine
Also available in roll format compatible with specified automated heat sealers, such as our Wasp or Chameleon XT

Overview
Simple protocol that is free of detergents
Fast processing time
Process a variety of inputs
Compatible with mass spectrometry and NMR spectroscopy
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit provides a fast and simple procedure for the isolation of total proteins from tissue, bacteria, yeast or mammalian cells without the use of SDS, Triton® X-100 and other detergents. Detergents are extensively used to prepare protein samples; however, these detergents have undesirable effects on downstream analysis. These effects include extraneous peaks in mass spectrometry, artifacts with chromatography and electrophoresis, interference with microinjection into cells and interference with protein immunization.
The Detergent-Free Total Protein Isolation Kit maintains high protein recovery and yields proteins that are 100% detergent-free. Purification is based on using Norgen’s proprietary resin together with Lysis Solution, followed by protein filtration using a filter column (provided). The purified proteins can be used in a number of downstream applications including mass spectrometry, SDS-PAGE, isoelectric focusing, NMR spectroscopy and more.
Each Lysis Tube is able to process up to 50 mg of tissue, 1010 bacterial cells, 109 yeast cells or 107 mammalian cells. Preparation time for 12 samples is less than 10 minutes.
Maximum Amount Of Starting Material: Tissues Animal Cells Bacteria Yeast
50 mg 1 x 107 cells 1 x 1010 cells 1 x 109 cells
Time to Process 12 Samples
Less than 10 minutes
Storage Conditions and Product Stability The Lysis Solution should be kept tightly sealed and stored at room temperature. Once opened, the solution should be stored at 4°C. This kit is stable for 2 years after the date of shipment.
Disulfide Biotin alkyne is an azide-activated cleavable biotin probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a biotin moiety linked to an alkyne group through a spacer arm containing a cleavable disulfide linker. Under reducing conditions (50 mM dithiothreitol, 10 mM 2-mercaptoethanol or 1% sodium borohydride), the disulfide bonds are cleaved, releasing the biotin tag and any avidin conjugate bound to it.

Isolation of exosomal RNA molecules from urine samples
Rapid and convenient spin-column protocol
Isolate inhibitor-free urinary microRNA for most downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Optional protocol for purification of exosomal proteins for western blot analysis
This kit provides a rapid spin column procedure for the isolation of exosomal RNA from urine samples. Users can simultaneously concentrate and isolate high quality exosomal RNA, including microRNA, for use in sensitive downstream assays such as RT-PCR, qRT-PCR, NGS, microarrays and more. The protocol can be completed in under 50 minutes. Urine volumes of 1 to 10 mL can be processed easily and rapidly. All sizes of RNA are recovered at an equal rate without the need for using hazardous chemicals like phenol.
Background
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 ascite fluids, among other biological fluids. These vesicles act as cellular messengers, conveying information to distant cells and tissues within the body. The exosomes contain cell-specific proteins, lipids and RNAs, which are transported to other cells, where they can alter function and/or physiology. 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. Recent work has demonstrated the presence of distinct subsets of microRNAs within exosomes which can inform about the cell type from which the exosomes are secreted. 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 urine.
Storage Conditions and Product Stability All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
