t-Boc-aminooxy-PEG6-propargyl

Introduction

Usages:
For isolation and enumeration of coagulase-positive staphylococci in foodstuffs.

Principle:
Tryptone, beef extract powder and yeast extract powder provides carbon and nitrogen sources, vitamins and growth factors; sodium pyruvate and glycine to stimulate the growth of Staphylococcus aureus; lithium chloride and potassium tellurite inhibit the non-staphylococcal microorganisms; containing lecithinase staphylococcal colonies produce degradation yolk make transparent circle, while the role of the lipase produced an opaque precipitate ring; coagulase-positive staphylococci can restore potassium tellurite and produce black colonies; agar is medium coagulant.

Introduction

Intended Use

For the enumeration of enterococci in water and other liquids by the membrane filtration technique.

Principle and Interpretation

The growth of the entire accompanying Gram-negative microbial flora is inhibited by sodium azide. Enterococci reduce 2,3,5-Triphenyl tetrazolium chloride (TTC) to give a red formazan inside the bacterial cell, their colonies are thus red. Nitrogen, minerals, and amino acids are provided by the tryptose whilst yeast extract supplies vitamins. Glucose acts as the carbon source, dipotassium phosphate buffers the medium, and agar-agar is the solidifying agent.

Formulation

Preparation

Dissolve 41.5 g in 1 L of purified water. Heat in boiling water and agitate frequently until completely dissolved. Sterilize by further heat for 20 minutes in the boiling water bath.

Quality Control

Cultural characteristics observed after incubation at 34-38°C for 40-48hours

Sorage and Shelf Life

Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of 3 years.

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.

Cell Culture Flask T225

Cell Culture Flask surface is very smooth based on precise molding technology and it gives clear view when examined with microscope.

Volume: 25mL75mL175mL225mL

PRODUCT FEATURES

• The product is made of medical grade USP CLASS VI polymer polystyrene
• The product is made under a 100,00- class dust-free manufacturing site
• Two kinds of product line up are providing.

For adherent cell culture: Initial adherence and proliferative property of cells via hydrophilic surface treatment.

For suspension cell culture: The surface is resistant to cell adherence, which minimizes damage or loss of cell.

• Large mouthed design makes easy operation of pipet or cell scraper. The surface of flask is uniform and smooth, hence the clear view can be obtained when microscopic observation.
• The hydrophobic filter cap can prevent invasion of fungi and bacteria without water absorb.
• Gamma radiation sterilization
• Non-Pyrogenic, DNase/Rnase free.
