DBCO-C3-PEG4-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction
Usage:
For selective isolation and culture of Staphylococcus aureus.
Principle:
Peptone and beef extract powder provides carbon, nitrogen, vitamins and minerals; D- mannitol to fermentable sugars; higher levels of sodium chloride to provide a higher osmotic pressure, suppress most non-staphylococcal microorganisms ; phenolsulfonphthalein as pH indicator; agar is medium coagulant. Typical pathogenic staphylococci (coagulase positive) D- mannitol produce acid fermentation and produce yellow colonies with a yellow halo, typically non-pathogenic Staphylococcus unfermented D- mannitol to form red colonies.
Formulation(per liter): Pancreatic digest of casein 5.0g Pancreatic digest of animal tissue 5.0g Beef Extract 1.0g Sodium Chloride 75.0g Mannitol 10.0g Phenol Red 0.025g Agar 15.0g Final PH 7.4±0.2
How to use: 1.Suspend 111g in 1L of distilled water , stirring heated to boiling to completely dissolve ,autoclave at 121℃ for 15 minutes. 2.Diluted and treated samples.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method,then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – silica gel column purification is much faster than ion exchange
High yield – up to 1.5mg plasmid can be binded in one column
Ultra low endotoxin – content of endotoxin is less than 0.1 EU/μg, which can be directly used for cell transfection and animal injection, etc.

Storage and Stability
The kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers,warm at 37℃ to dissolve. After addition of RNase A,Buffer P1 is stable for 6 months when stored at 2–8°C.

Recommended Use: Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage: This kit is stable for 2 years after the date of shipment.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
