Propargyl-PEG3-CH2CO2H is an PEG linker with an alkyne and carboxylic acid set of functional groups. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The carboxylic acid can react with primary amines to form stable amide bonds; activator (e.g. EDC, or HATU) is needed.

DBCO-PEG4-PC represents a photocleavable, PEG linker consisting of a DBCO group that can be used for copper-free Click Chemistry reactions. This structure allows for efficient photorelease of linked molecules, typically achieving over 90% cleavage in 5-25 minutes using a near-UV lamp. The PEG4 spacer increases the hydrophilicity of the compound.

Description
Q-PAGE™ TGN (Tris-Glycine Novel) Precast Gels are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, Q-PAGE™ TGN Precast Gels perform enhanced speed, better separation, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in Q-PAGE™ TGN series, however, are similar with typical Laemmli Tris-HCl gels, and thus Q-PAGE™ TGN Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses.
Q-PAGE™ TGN Precast Gels are available in gradient (4 to 15%) and fixed (10%) concentrations of polyacrylamide in 12- and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP4XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP5XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.
Key Features
Storage and stability
Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.
Do not freeze Q-PAGE™ Precast Gels. Remove tape and comb before electrophoresis.
Keep Q-PAGE™ Precast Gels flat during storage.

This kit provides a rapid spin column method for the isolation and purification of genomic DNA from both Gram-negative and Gram-positive bacteria in milk samples. It can also be used to process challenging milk samples such as Mastitic milk for example. The kit is highly sensitive and can isolate DNA from a cell density of as little as 10 bacteria contained in 1 mL of milk. Genomic DNA is isolated in 45 minutes, free of inhibitors and ready for any number of downstream applications including PCR, qPCR and Southern Blot analysis, sequencing and more.
