N-(endo-BCN-PEG2-amido-PEG3)-N-bis-(PEG3-Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is is a multi-functional PEG linker with six terminal propargyl groups and a BCN group. The propargyl groups enables formation of triazole linkage with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry. The BCN group can react with azide -tagged compound or biomolecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Usages:
For determination of coliform confirmatory test for multi-tube fermentation.
Principle:
Peptone provide carbon and nitrogen sources; lactose as fermentable sugars; ox bile powder and brilliant green inhibit the non-Enterobacteriaceae.
Formulation (per liter):
Peptone: 10g
Lactose: 10g
Ox bile powder: 20g
Brilliant green: 0.0133g
Final pH7.2 ± 0.2
How to use:
1.Suspend 40g of the product, add 1 L of distilled water, stirring heated to boiling until completely dissolved, packed in a test tube with a small inverted tube, autoclave at 121 ℃ for 15min, cool to room temperature and set aside.
2.Sample handling and dilution. Slightly.
3.Transplanted LST broth tube to brilliant green lactose bile broth tube by using a inoculating loop.
4.the tube was placed in an incubator culture at 36 ± 1 ℃ for 24h.
5.Observe the results. Press production trachea number, check table report MPN MPN value per gram (mL) sample of coliform bacteria.
Quality control:
Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows:
