Overview
Detection kits for E.coli O157:H7
Available in TaqMan format for analysis
E. coli O157:H7 is a rod-shaped, gram negative bacterium. It is an enterohemorrhagic strain of the common E. coli bacterium and infection by the O157:H7 strain is commonly associated with hemorrhagic colitis. E. coli O157:H7 is recognized by its somatic (cell wall) antigen (O157) and its flagella antigen (H7). In addition, E. coli O157:H7 is known to produce Shiga-like toxins, which cause severe symptoms. While most patients can recover from the infection, up to 15% of the patients may develop hemolytic uremic syndrome, a type of kidney failure that could be fatal. Infection of E. coli O157:H7 usually results from consumption of poorly prepared food including undercooked meat (particularly ground beef), untreated water or raw unpasteurized milk.

AAV Purification from any input – cell fraction or media fraction
High AAV recovery, up to 90%
No specialized equipment needed
Purification from a variety of AAV serotypes (including AAV6 and AAV9)
Yields highly active AAV for in vivo and in vitro experiments
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
Recombinant adeno-associated virus (AAV) vectors are highly promising tools for both in vitro and in vivo gene transfer. Norgen’s AAV Purification Kits provide fast and simple procedures for concentrating and purifying AAV vectors from cell lysate and cell culture media. Purification is based on precipitation onto Norgen Biotek’s proprietary resin. Contaminating cellular debris is largely removed from the sample via a centrifugation step, while contaminating DNA and RNA is reduced using enzymatic digestion. AAV vector purified in this manner is highly active for use in in vitro and in vivo transduction experiments.
AAV Purification Kit
Norgen’s AAV Purification Kit contains sufficient materials for 15 preparations (33.5 mL per prep of supernatant (SN) or a total of 500 mL of supernatant input). Approximately 1 mL of cell pellet can be purified per prep, up to a maximum of 15 mL of cell pellet in total for the entire kit. Up to 33X sample concentration.
AAV Purification Mini Kit
Each spin column is able to concentrate and purify AAV from 0.5-8 mL of cell pellet, cell culture media, or cells and culture media mixed together. Up to 50X sample concentration. AAV vector purified in this manner is highly active for use in in vitro transduction experiments, and is eluted into a small volume (200 µL). Preparation time for 4 samples is 1.5 hours, with 45 minutes of hands-on time.
AAV Purification Midi Kit
Each spin column is able to concentrate and purify AAV from 8 mL up to 45 mL of input consisting of cell pellet, cell culture media, or cells and culture media mixed together. Up to 50X sample concentration. AAV vector purified in this manner is highly active for use in in vitro transduction experiments, and is eluted into a small volume (1 mL). The kit may be used to purify up to 8 x 25 mL or 4 x 45 mL of samples using the included columns. Preparation time for 4 samples is approximately 2 to 2.5 hours, with 1.5 hours of hands on time.
AAV Purification Maxi Kit (Slurry Format)
Each spin column is able to concentrate and purify AAV from 45 mL to 90 mL of input consisting of cell pellet, cell culture media, or cells and culture media mixed together. Up to 200X sample concentration. AAV vector purified in this manner is highly active for use in in vitro transduction experiments, and is eluted into a small volume (1-10 mL) using the optional concentration step. The kit may be used to purify up to 1 x 900 mL samples or 10 x 45-90 mL samples using the included columns. Preparation time for 1 x 900 mL sample is approximately 2.5 to 3.5 hours, with an optional concentration step requiring an additional 30 min.
