Propargyl-PEG7-alcohol

N-(t-butyl ester-PEG2)-N-bis(PEG2-propargyl) is a multi-functional PEG linker with two terminal propargyl groups and a t-butyl ester. The propargyl groups enables formation of triazole linkage with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry. The t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG23-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 the water solubility of the compound.

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
