endo-BCN-PEG2-NHS ester

N-Boc-N-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are combined together at a Boc-protected secondary amine. Terminal alkynes are most commonly used in copper click chemistry with azides to form stable triazoles with the target molecule. The secondary amine may be deprotected under acidic conditions to allow for alkylation at that position, increasing the molecule’s structural complexity. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

The Lactose/Galactose (Rapid) test kit is used for the rapid test of lactose, D-galactose and L-arabinose in food and plant products. Galactose dehydrogenase can be used the measurement and analysis of both D-galactose and L-arabinose. Suitable for the analysis of lactose in “low-lactose” or “lactose-free” samples which contain high levels of monosaccharides. The reagents provided in this kit are also suitable for use with AOAC method 2006.06 – Lactose in milk.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.  This can be readily accommodated using the MegaQuant^TM  Wave Spectrophotometer (D-MQWAVE).

Overview

• Rapid spin column purification of genomic DNA from viable yeast cells, fungal spores or mycelium, and bacteria including Gram-positive
• Bead tubes (provided) allow for effective mechanical homogenization
• Purified DNA is of high quality and integrity and compatible with any sensitive downstream applications such as PCR, qPCR, RFLP and more

These kits provide fast and reliable procedures for the purification of genomic DNA from viable yeast cells, fungal spores or mycelium, and bacteria including Gram-positive. Genomic DNA is efficiently extracted from the cells by a combination of heat treatment, detergents and Bead Tubes (provided). An optional lyticase treatment allows for improved DNA yields with certain fungal and yeast species. Recovered genomic DNA is of excellent yield and purity for any downstream application including PCR, qPCR, Restriction Fragment Length Polymorphism (RFLP), Amplified Fragment Length Polymorphism (AFLP), sequencing, SNP analysis and more.

Fungi/Yeast Genomic DNA Isolation Kit (Spin Column)

This kit provides rapid spin column purification of genomic DNA from viable yeast cells, fungal spores or mycelium, and bacteria including Gram-positive. Preparation time for a single sample is less then 30 minutes, and each kit contains sufficient materials for 50 preparations.

Fungi/Yeast Genomic DNA Isolation 96-Well Kit (HT)

Norgen’s Fungi/Yeast Genomic DNA Isolation 96-Well Kit provides a fast, reliable and simple procedure for high throughput isolation of DNA from viable yeast cells, fungal spores or mycelium and Gram-positive bacteria. The purification could be performed on either a vacuum manifold or using centrifugation. Complete 96 purifications in 40 minutes.
