DBCO-PEG6-NHS ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction

Usages:
For isolating lactose-fermenting Gram-negative enteric bacilli.

Principle:
Peptones are sources of nitrogen and other nutrients. Lactose is a fermentable carbohydrate. When lactose is fermented, alocal pH drop around the colony causes a color change in the pH indicator (neutral red) and bile precipitation. Bile salts,bile salts no. 3, oxgall and crystal violet are selective agents that inhibit growth of gram-positive organisms. Agar is the solidifying agent.

Formulation（per liter）:

How to use：
1.Suspend 50 g in 1 L of distilled or deionized water. Heat to boiling to dissolve completely. Autoclave at 121°C for 15 minutes.

2.Transfer 1 mL of Soybean–Casein Digest Broth to 100 mL of MacConkey Broth, and incubate at 42 to 44 for 24 to 48 hours. Subculture on a plate of MacConkey Agar at 30 to 35 deg.C for 18 to 72 hours.

Quality control：
          　　

Storage: Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of three years.

Specifications: 250g/bottle

Introduction

This product provide fast and easy methods for purification of total DNA from whole blood, plasma, serum, buffy coat, bone marrow, other body fluids, lymphocytes, cultured cells. There is no need to use toxic phenol chloroform extraction or time-consuming alcohol precipitation. The extraction process finish in 40 minutes. Purified DNA includes genomic DNA, mitochondrial DNA, viral DNA (e.g. HBV), or DNA from other parasitic microorganisms. The obtained DNA can be directly used in PCR, viral DNA detection and other experiments.

This kit can use on manual protocol or 16/32/48 channel automated extraction system. No need to pause for the addition of binding solution (not applicable to 96/192 instruments)

Storage and Stability

Proteinase K Powder should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these condition.
