Propargyl-PEG1-NHS ester

Introduction

Intended Use

Used for the selective isolation and culture of Listeria monocytogenes.

Principle and Interpretation

Columbia Blood Agar Base provide carbon and nitrogen sources, vitamins and growth factors，maintains balanced osmotic pressure; Listeria hydrolyzes aesculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.

Formulation

Ingredients	/liter
Columbia blood agar base	39.0 g
Aesculin	1.0 g
Ferric ammonium citrate	0.5 g
Lithium chloride	15.0 g
pH7.0±0.2 at 25°C

Preparation

Weigh 55.5 g of this product, add 1000 mL of distilled water or deionized water, stir, heat and boil until completely dissolved, divide into Erlenmeyer bottles, sterilize at 121℃ for 15 min. Cool to about 50℃, add 1 bottle of SR0500 supporting reagent A and 1 bottle of B per 100 mL, mix well and set aside.

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.

DBCO-NHCO-PEG13-NHS ester is a long chain PEG linker containing NHS ester that is able to react specifically and efficiently with primary amines to form astable amide bond. The hydrophilic PEG13 arm improves water solubility and can also provide a long and flexible connection that minimizes steric hindrance during ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview

• High yield and high purity DNA ready for any application
• Available in a variety of formats to properly suit your needs
• Compatible with blood collected on a variety of commercially available tubes

These kits allow for the isolation of DNA from the blood of various species, including humans and will recover genomic DNA, mitochondrial DNA, viral DNA and bacterial DNA. The purified DNA is of excellent quality and yield and completely compatible with any downstream application including PCR, qPCR and genotyping.

Blood DNA Isolation Mini Kit

Norgen’s Blood DNA Isolation Mini Kit is designed for the rapid preparation of DNA from up to 200 µL of whole blood using a rapid spin column protocol. Preparation time for a single sample is less than 30 minutes and each kit contains sufficient materials for 50 preparations.

Blood DNA Isolation Midi Kit

Norgen’s Blood DNA Isolation Kit is designed for the rapid spin column preparation of DNA from 0.3 to 2 mL volumes of whole blood. Preparation time for a single sample is less than 30 minutes, and each kit contains sufficient materials for 20 preparations.

Blood DNA Isolation Maxi Kit

This kit is designed for the rapid preparation of DNA from 3 mL up to 10 mL of whole blood. Preparation time for a single sample is less than 30 minutes.

Blood DNA Isolation 96-Well Kit (High Throughput)

This kit provides a rapid method for the high-throughput isolation of DNA from up to 200 µL of whole blood. Fast and easy processing using either a vacuum manifold or centrifugation.

Blood DNA Isolation Kit (Magnetic Bead System)

Norgen’s Blood DNA Isolation Kit (Magnetic Bead System) is designed for the rapid preparation of genomic DNA from up to 200 µL of whole blood from various species, including human. Purification is based on magnetic beads as the separation matrix. Norgen’s magnetic beads bind DNA under optimized salt concentrations and releases the bound DNA under low salt and slightly alkali conditions. The genomic DNA is preferentially purified from other cellular proteinaceous components. Typical yields of genomic DNA will vary depending on the cell density of the blood sample. The purified genomic DNA is fully digestible with all restriction enzymes tested, and is completely compatible with downstream applications including real-time PCR, NGS and microarray analysis.

Blood DNA Isolation 96-Well Kit (High Throughput Magnetic Bead System)

96-well format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.
