DBCO-PEG12-acid is an analog of DBCO-Acid with hydrophilic PEG linker and a DBCO group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
Overview
Purify all sizes of RNA (including microRNA) without the need for phenol
Isolate and detect total RNA from 1 mL and up to 50 mL urine
Provides high-quality RNA for sensitive applications – isolate RNA from as little as 100 cells
Rapid processing time from sampling to downstream testing
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit provides a rapid spin column method for the isolation and purification of total RNA (including microRNA) from exfoliated cells that have been shed into the urine from the urinary tract. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The RNA is preferentially purified from other cellular components such as proteins, as well as from the contaminating species found in urine such as glucose and salts, without the use of phenol or chloroform. The purified RNA is of the highest integrity and can be used in a number of downstream applications including real-time RT-PCR, qRT-PCR, Northern blotting, NGS, and expression array assays. Multiple samples can be processed in 20 minutes.
Background
RNA biomarkers from exfoliated cells can be used as non-invasive tools for a number of diagnostic and research applications including the diagnosis and monitoring of bladder, kidney, or other urinary-tract cancers.
~1μg RNA per 1 x 105 cells (For Exfoliated Cells – Varies due to cell density sample)~0.5μg RNA per 1 x 107 cells(For Bacteria – Varies due to cell density sample)
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
ArcticZymes’ Shrimp Alkaline Phosphatase (SAP), including its recombinant version (rSAP), is the gold standard and the first heat-labile, all-purpose alkaline phosphatase on the market.
Originally isolated from Pandalus borealis (Arctic shrimp), it has been purified from a recombinant source since 2010. Unlike other alkaline phosphatases, rSAP can be fully inactivated by a short heat treatment of 15 minutes at 65°C.
This added convenience through complete heat inactivation has made SAP one of the most sold DNA modifying enzymes.
For added flexibility, especially when lyophilisation may be desired, rSAP is also available in a Glycerol FREE format. First launched in 1993, SAP’s unique features continue to make it a valuable tool in various applications.
Key Features
Gold standard heat labile, all-purpose alkaline phosphatase.
Completely inactivated after 5 min at 65°C or 1 min at 75°C.
Robust: Active in most restriction enzyme buffers, no need for supplemental zinc or other additives for activity.
Simple, hassle-free dephosphorylation of DNA, RNA, dNTPs and proteins for subsequent use in cloning or end-labelling of probes.
No vector purification necessary.
Easy inactivation of unincorporated dNTPs in PCR products prior to DNA sequencing or SNP analysis.
Ideal for MALDI-TOF, cloning, HLA typing, genotyping and sequencing.
Preparing substrate in protein kinase studies.

Escherichia coli (E.coli) O157:H7 Quantified Bacterial DNA Standards
Product Info
Document
Product Info
Overview
Quantified standard to be used as a positive control or PCR quantification standard
Vigorously quantified using multiple methods
Includes partial sequence of STX-1 subunit A, and STX-2 subunit A genes (please refer to product insert for more details)
Compatible with E. coli O157:H7 TaqMan PCR Detection Kit and E. coli O157:H7 TaqMan PCR Detection Probe/Primer and Control Set
E. coli O157:H7 is a rod-shaped, gram negative bacterium. It is an enterohemorrhagic strain of the common E. coli bacterium and infection by the O157:H7 strain is commonly associated with hemorrhagic colitis. E. coli O157:H7 is recognized by its somatic (cell wall) antigen (O157) and its flagella antigen (H7). In addition, E. coli O157:H7 is known to produce Shiga-like toxins, which cause severe symptoms. While most patients can recover from the infection, up to 15% of the patients may develop hemolytic uremic syndrome, a type of kidney failure that could be fatal. Infection of E. coli O157:H7 usually results from consumption of poorly prepared food including undercooked meat (particularly ground beef), untreated water or raw unpasteurized milk.
Norgen’s E. coli O157:H7 Quantified Bacterial DNA Standards are cloned fragments of the two Shiga-like toxin regions purified using Norgen’s sample preparation technology. They include partial sequences of STX-1 subunit A gene and STX-2 subunit A gene. Please refer to Appendix A for sequence information. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as positive controls or PCR quantification standards for E. coli O157:H7. This product is compatible with Norgen Biotek’s E. coli O157:H7 Taqman PCR Detection Kit (Cat. TM41350) and E. coli O157:H7 Taqman PCR Detection Probe/Primer and Control Set (Cat. TM41310).
Storage Conditions Upon receipt, store Norgen’s E. coli O157:H7 Quantified Bacterial DNA Standards at -20°C or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20°C or lower.
