DBCO-PEG4-Butyraldehyde is a click chemistry PEG reagent containing a terminal butylraldehyde group. Butyraldehyde reacts with hydrazide to form a stable hydrazone linkage or with alkoxyamines to form a stable oxime bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

Fig 1. Only three steps will be need for Sample Preparation and only 20 minitutes will be taken for Sample Preparation.
Fig 2. Seven concentration samples of 5fg/μL, 10fg/μL, 20fg/μL, 30fg/μL, 300fg/μL, 3pg/μL, 30pg/μL, 300pg/μL were detected. CV of each concentration was < 30%, Regression coefficient associated with standard solutions was 0.99975, and amplification efficiency was 100.068%.
Fig 3. Four concentration samples of 5fg/μL, 10fg/μL, 20fg/μL, and 30fg/μL were detected, and 10 multiple holes were detected for each concentration. The detection values of 5fg/μL and above were CV ＜30%.
Fig 4. DNA recovery can be determined by including samples spiked with known DNA amounts which are prepared from the corresponding DNA standards. Typically, the range for this value varies from 70% to 130%.

The resDNASEQ E.coli Residual DNA Quantitation kit is designed for the quantification of residual DNA from E. coli, in cell lines which are used for production of biopharmaceutical products. The resDNASEQ E.coli Residual DNA Quantitation kit use TaqManTM quantitative PCR to perform rapid, specifc quantitation of femtogram levels of residual host-cell or plasmid DNA. The kit was developed to meet the sensitivity requirements defined by WHO (10 ng E. coli DNA per therapeutic dose).

Norgen’s FFPE RNA Purification Kits provide a rapid method for the isolation and purification of total RNA (including microRNA) from formalin-fixed paraffin-embedded (FFPE) tissue samples in as little as 1 hour. Using formalin to fix tissues leads to crosslinking of the RNA and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the RNA over time. Norgen’s FFPE RNA Purification Kits provide conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of RNA. These kits are able to purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA), depending on the age of the FFPE tissue as fragmentation of the RNA is known to occur over time. The RNA is preferentially purified from other cellular components without the use of phenol or chloroform.
FFPE RNA Purification Kit (Spin Column)
Maximum loading volume of 650 μL per column, and a maximum binding capacity of 50 μg per column.
FFPE RNA Purification 96-Well Kit (High Throughput)
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Maximum loading volume of 400 μL per well, and a maximum binding capacity of 50 μg per well.
