Bis-PEG11-DBCO

Overview

• Rapid AAV DNA extraction and quantification can be completed in 2 hours 
• Universal qPCR assay targeting the AAV2 ITR enables quantification of most AAV vector constructs
• Purified DNA standard enables easy comparison of data between different lab groups
• Non-plasmid based standard prevents quantification artifacts due to insufficient melting of plasmid sequences
• DNAse digestion step aids in eliminating non-viral DNA
• Minimal sample handling for maximum AAV DNA recovery

Norgen’s AAV Quantification Kit is designed for the detection of adeno-associated virus (AAV) inverted terminal repeat (ITR) sequences in a real-time PCR based on the use of TaqMan® technology. A purified standard based solely on the AAV2 ITR sequence purified using Norgen’s proprietary silicon carbide technology simplifies the generation of a reliable standard curve for AAV quantification. Avoidance of a plasmid based standard eliminates problems associated with efficient melting of the ITR sequence due to coupling of the ITR to the much longer plasmid sequence, as well as variability due to rearrangements/duplications/deletions of the recombination prone ITR. An easy and rapid method for viral DNA extraction simplifies the step of obtaining AAV DNA while simultaneously eliminating contaminating non-encapsidated DNA.  Norgen’s AAV Quantification Kit can facilitate pre-clinical studies that require accurate vector titration as well as interlab comparisons of vector quantities. This kit is designed for research use only and not for use in diagnostic procedures.

Storage Conditions and Product Stability
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots. All reagents can be stored for 1 year at -20°C without showing any reduction in performance.

Description 

The PM2600 ExcelBand™ 3-color High Range Protein Marker is a ready-to-use three-color protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine Buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and 10 to 235 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). The PM2600 3-color High Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.

Features

• Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.
• Two reference bands — 75 kDa (red) and 25 kDa (green)

Contents 

Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol). 

Quality Control 

Under suggested conditions, PM2600 ExcelBand™ 3-color High Range Protein Marker resolves 12 major bands in 15% SDS-PAGE (Tris-Glycine buffer, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane. 

Storage

4°C for 3 months
-20°C for long term storage

Diazo Biotin-PEG3-alkyne is useful for introducing a biotin moiety to azide-containing biomolecules using Cu(I)-catalyzed Click Chemistry. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Diazo allows efficient release of captured biotinylated molecules from streptavidin using sodium dithionite (Na2S2O4). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
