DBCO-PEG9-DBCO is a click chemistry linker with two DBCO groups and a hydrophilic PEG spacer arm. DBCO is reactive with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. The hydrophilic PEG9 arm increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples.
Organophosphate compounds (OP) account for the largest class of rural and urban poisons in the world that are used to kill pests but can also be toxic to humans. OPs cause toxicity by means of blocking the acetylcholinesterase enzyme (AchE). The AChE-directed OPs react with a serine residue that is located at the catalytic site found within the AChE gorge. The OP targeted enzyme is no longer able to hydrolyze ACh, resulting in the buildup of ACh in the nerve synapse. This effect causes excessive excitation of the nerves, producing uncoordinated movements, tremors, paralysis and death. Both synthetic and natural(Guanitoxin) organophosphates are dangerous to humans — exposure can lead to visual, coordination, muscular, and neurological deficiencies, and in some cases even to death. In turn, exposure to OP is a significant public health concern which would significantly benefit from an improved detection platform.
Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples. For solid samples a simple sample preparation method is performed. The ability to detect Organophosphate is performed is simple and sensitive. The reaction uses a chromophore that can be detected by eye. In the presence of Organophosphate, the rate of chromophore production is reduced in a concentration dependent fashion. The higher the concentration of Organophosphate the less color is produced.

Description
The PM2800 ExcelBand™ 3-color Extra Range Protein Marker is a ready-to-use three-color protein standard with 13 pre-stained proteins covering an extra range of molecular weights from 10 to 310 kDa in Tris-Glycine buffer (9 to 290 kDa in Bis-Tris (MOPS) buffer and 10 to 290 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for three reference bands (one green and two red bands at 25 kDa and 75, 310 kDa respectively) when separated on SDS-PAGE in Tris-Glycine buffer. The PM2800 ExcelBand™ 3-color Extra Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for approximating the size of proteins. The marker is supplied in the gel loading buffer and is ready to use. Do NOT heat, dilute, or add reducing agents before loading.
Features
Contents
Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25℃), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol).
Quality Control
Under suggested conditions, PM2800 3-color Extra Range Protein Marker resolves 13 major bands in 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

HiPure Bacterial RNA Kit uses silica gel column purification to simplify the extraction. The whole process does not require phenol chloroform extraction and time-consuming alcohol precipitation. The kit is suitable for efficiently extracting RNA from various bacterial samples. The purified RNA can be directly used for RT-PCR, Northern hybridization, etc. The kit has included lysozyme and glass beads, which can be used to treat gram-negative bacteria which is easy to be lysed, as well as gram-positive bacteria which is hard to be lysed, including enterococcus faecalis, staphylococcus, etc.

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Storage and Stability
The kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Due to the lack of antibacterial agents, RNase Free Water may be contaminated by bacterial or fungal when placed or operated at room temperature. It is recommended to pack and store at 2-8°C to reduce contamination.
