Propargyl-PEG3-Ms

Sulfo DBCO-PEG4-Maleimide is a water-soluble click chemistry reagent with a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Acid-PEG2)-N-bis(PEG2-propargyl) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.

Overview

• RNA/microRNA/DNA/Proteins are preserved for more than 2 years at room temperature in Norgen’s Urine Preservative
• Compatible with most DNA, Total RNA, microRNA and protein isolation methods
• Preservative is available in a single dose liquid format (ampule)
• Preservative is also available in a dried format in tubes – Urine Collection and Preservation Tubes
• Urine Collection and Preservation Devices are available in 4 convenient sizes: 5 cc tubes, 15 cc tubes, 50 cc tubes, and 120 cc cups

Norgen’s Urine Preservative is designed for the rapid preservation of DNA, RNA, microRNA and proteins from fresh urine samples. In addition, the Urine Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins.

Norgen’s Urine Preservative is available in 2 convenient formats:

1.  Urine Preservative Single Dose Ampules
With this product Norgen’s Urine Preservative is supplied in a liquid format in single dose ampules. The user simply collects 5 – 50 mL of urine into a urine collection container and adds the contents of the Urine Preservative Single Dose (Cat# 18126). The urine and preservative are then mixed, and the urine nucleic acids and proteins are preserved at room temperature.

2.  Urine Collection and Preservation Tubes
Norgen’s Urine Preservative is also available in a dried format in Norgen’s Urine Collection and Preservation Tubes. The user simply collects urine into the tubes and mixes gently until the orange preservative pellet in the tube has dissolved. Norgen’s Urine Collection and Preservation Tubes are available in 3 convenient sizes:

• 5 cc tubes, 1 – 5 mL of urine
• 15 cc tubes, 5 – 15 mL of urine
• 50 cc tubes, 5 – 45 mL of urine
• 120 cc cup, 100 – 120 mL of urine
