DBCO-S-S-acid is a cleavable reagent for introduction of a carboxylic acid moiety to azide-containing biomolecules using copper-free Click Chemistry. PEG spacer arm provides better solubility to the labeled molecules in aqueous media. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP.

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.
MutL Homolog 1 (MLH1) is a protein involved in the mismatch-repair pathway. This protein is commonly associated with hereditary non-polyposis colorectal cancer, as the MLH1 gene is frequently mutated in patients with this cancer. Studies have shown MLH1 to be deficient in a high percentage of patients with microsatellite instability, as well as endometrial and ovarian cancers. Use of Anti-MLH1 is optimized when paired in an IHC panel with MSH6, MSH2, and PMS2. Anti-MLH1 is useful in the detection of MLH1 in a number of normal and neoplastic tissues, and for identifying a loss of MLH1 in tumors that are microsatellite-unstable.
