Tri(propargyl-PEG10-NHCO-ethyloxyethyl)amine

Name of Product

Trichinella spiralis – IgG ELISA

Catalog Number

9750

Short Info

Trichinellosis is caused by Trichinella spiralis, a parasitic nematode of pork, horse and wild animals. Humans can be infected by eating raw or undercooked meat from infected animals. Most infected people do not show any symptoms. However, in some cases, symptoms appear during intestinal stage (diarrhea and abdominal pain) and muscular stage (muscle pain, fever, edema). Diagnosis is based on signs and symptoms, but in many cases it is not conclusive for the diagnosis. Serological assays have an important place on the final diagnosis of the disease. The ELISA kit has shown appropriate performance for the serological screening of trichinellosis.

This product is manufactured by Bordier Affinity Products in Switzerland and distributed in Germany exclusively by Milenia Biotec.

Method/Platform

ELISA in microplate format

Range/Assay Sensivity

95% sensitivity, 98% specificity

Test Principle

The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Trichinella spiralis excreted/secreted (E/S) larval antigens. Specific antibodies in the sample will bind to these antigens and washing will remove unspecific antibodies. The presence of parasite specific antibodies is detected with a Protein A – alkaline phosphatase conjugate. A second washing step will remove unbound conjugate. Revealing bound antibodies is made by the addition of pNPP substrate which turns yellow in the presence of alkaline phosphatase. Color intensity is proportional to the amount of Trichinella spiralis specific antibodies in the sample. Potassium phosphate is added to stop the reaction. Absorbance at 405 nm is read using an ELISA microplate reader. The test can be performed with automatic systems, but this must be validated by the user.

Overview

• Purification and enrichment of intact cell culture media exosomes for functional studies
• Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
• Versatile cell culture media input volumes
• No phenol extractions, Proteinase K treatment, nor carrier RNA required
• No time-consuming ultracentrifugation, filtration nor special syringes required
• No precipitation reagents nor overnight incubation required
• Pure exosomes are purified and are free from any other RNA-binding proteins
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin
• The purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services

Norgen’s Cell Culture Media Exosome Purification and RNA Isolation Kits constitute an all-in-one system for the purification of exosomes and the subsequent isolation of exosomal RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The kit is designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. 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, the 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. 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.

Overview

• Excellent separation and purification of cytoplasmic and nuclear RNA
• Convenient and fast spin column format
• High quality and yield of RNA
• Isolate full diversity of RNA (including microRNA) without phenol
• Purified RNA is ready for any application including RT-PCR, qRT-PCR, RNA-Seq, arrays and more
• Cytoplasmic RNA is free of DNA and ready for direct use in RT-PCR/qRT-PCR
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

This kit provides a rapid method for the isolation and purification of both cytoplasmic and nuclear RNA from cultured animal cells and small tissue samples. The kit can be used to isolate all sizes of RNA from the cytoplasmic and nuclear RNA fractions, including all small RNA species without any requirement for phenol.   Included in the kit are sufficient reagents to perform either 50 cytoplasmic RNA preparations or 25 cytoplasmic and 25 nuclear RNA preparations.   Ten samples can be processed in approximately 45 minutes.  This kit is also available in a 100 prep size.    

Background

In certain circumstances it is desirable to be able to isolate fractionated RNA as opposed to total RNA. For example, it may be preferable to isolate only mature, cytoplasmic RNA for some studies on expression profiling. Alternatively it may be desirable to isolate nuclear RNA in order to investigate and study pre-processed (non-spliced) RNA. Furthermore, this kit can be used to isolate RNA for downstream applications where it is necessary to avoid DNA contamination, since the cytoplasmic fraction has been shown to be free of all traces of genomic DNA.
