Propargyl-PEG4-methylamine

Introduction

Usages:
For the growth of pathogenic and non-pathogenic microorganisms.

Principle:
Polypeptone provide carbon and nitrogen sources, vitamins and growth factors; Neisseria starch can promote the growth characteristics and enhanced hemolytic streptococci; sodium chloride to maintain osmotic balance; agar as culture medium coagulant.

Formulation (per liter):
Peptone: 10g
Beef extract powder :10g
Sodium chloride: 5g
Agar :15g
Final pH 7.4 ± 0.2

How to use:
1. Suspend 40g of the product, adding 1 L of distilled or deionized water, ,heated to boiling stirring until completely dissolved, dispensing into flask, 121 autoclaved 15min.
2.After the medium is cooled to about 50 , sterile procedures, basal medium was added per 100mL defibrinated sheep or rabbit blood 5-10mL, shake pour plate; also dispensing sterile tubes set into the slope. Spare.
3. take the bacteria to be tested fresh pure cultures inoculated crossed or coated on the plate, set the temperature of the incubator training requirements were cultured for a predetermined time.
4. Observe the results.

Quality control:
The following were inoculated after 36 ± 1 for 24h , the results are as follows:
bacteria name bacteria No. growth status colony characteristics
Escherichia coli ATCC25922 not good hemolysis

Staphylococcus aureus, ATCC6538 good β-hemolytic

Beta-hemolytic streptococcus CMCC (B) 32210 good β-hemolytic

Streptococcus pneumoniae CMCC (B) 31001 good α-hemolytic

Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.

Bis-propargyl-PEG18 has two propargyl groups at both ends. These propargyl groups reacts with azide compounds or biomolecules to form stable triazole linkages under the catalyzation of copper. The hydrophilic PEG units enhance the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
