DBCO-PEG12-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose.

Introduction

Intended Use

For the selective isolation and culture of Listeria monocytogenes.

Principle and Interpretation

Peptone provides the carbon and nitrogen sources necessary for growth; yeast extract powder and starch provide carbon and nitrogen sources, vitamins and growth factors; sodium chloride can maintain a balanced osmotic pressure; glucose provides a carbon source; Listeria hydrolyzes esculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; mannitol is a fermentable sugar, and phenol red is a pH indicator; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.

Preparation

Weigh 68.9g of dry powder of this product, add 1L of distilled water or deionized water, stir, heat and boil until completely dissolved, divide into Erlenmeyer bottles, sterilize at 121℃ for 15min, cool to room temperature and set aside. Heat to dissolve agar before use, cool to 50℃, add 1 tube of supporting reagent (SR0140) per 100mL of basal culture medium, shake well and pour into sterilized culture dish.

Quality Control

The following quality control strains were inoculated and cultured at 35-37℃ for 24h. The results are as follows:

Quality control strains	Growth
Listeria monocytogenes ATCC19115	Gray-green colonies with a black depression in the center and black surrounding
Enterococcus faecalis ATCC29212	–
Escherichia coli ATCC25922	–

Storage and Shelf Life

2-30℃，Keep container tightly closed, avoid direct sunlight.

Use before expiry date on the label.

 Precautions

1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort

2. Keep container tightly closed after using to prevent clumping.

Waste Disposal

Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.

Overview

• Adenovirus Purification from any input – cell fraction or media fraction
• Rapid purification within 2 to 4.5 hours
• No specialized equipment needed (ultracentrifuge not required)
• Purify adenovirus cell culture supernatant from 1 mL to 33.5 mL input per prep
• Purify adenovirus cell pellet from 1 mL of input per prep
• Up to 25X sample concentration
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

Adenoviral vectors are useful tools for both in vitro and in vivo gene transfer, and oncolytic viruses based on adenovirus are highly promising for cancer treatment. Norgen’s Adenovirus Purification Kit provides a fast and simple procedure for concentrating and purifying adenoviral vectors from cell lysate and cell culture media. Purification is based on spin column chromatography using Norgen’s proprietary resin as an ion exchanger.  Contaminating cellular debris is largely removed from the sample via a centrifugation step, while contaminating DNA and RNA is reduced using enzymatic digestion. Adenoviral vectors purified in this manner are highly active for use in transduction experiments.

Norgen’s Adenovirus Purification Kit contains sufficient materials for 15 preparations (33.5 mL per prep of supernatant 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.
