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.

Introduction

Usages：
Determination of coliform and fecal coliform for multiple tube fermentation.
 
Principle:
Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
 
Formulation (per liter):
Trypticase:20g
Sodium chloride: 5g
Lactose:5g
Potassium dihydrogen phosphate: 2.75g
Dipotassium hydrogen phosphate :2.75g
Sodium lauryl sulfate 0.1g
Final pH6.8 ± 0.2
 
How to use:
1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby .
2.Sample handling and dilution.
3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL.
4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h.
5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if  gas production then will have to make further confirmed by experiments.
 
Quality control:
Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows:
Bacterial Name                 Bacterial No.          Growth Status       Gassing
Escherichia coli                ATCC25922               good              +
 
Salmonella typhimurium        CMCC (B) 50115            good             —
 
Staphylococcus aureus          ATCC6538                inhibited          —
 
 
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
