Description
YesBlot™ Western Marker I is a ready-to-use mixture with ten IgG-binding proteins covering a wide range of molecular weights from 15 to 200 kDa in Tris-Glycine buffer. YesBlot™ Western Marker I performs dual functions. First, it contains 4 pre-stained proteins (10, 25, 45 and 70 kDa) for monitoring protein separation during SDS-PAGE, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for approximating the protein size. Second, ten IgG-binding proteins can be immuno-detected on film or by CCD imaging. YesBlot™ Western Marker I is compatible for chemiluminescent, fluorescent, chromogenic or other detection systems. In addition, YesBlot™ Western Marker I has two reference bands with enhanced intensity (at 30 kDa and 80 kDa). 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
Direct visualization — 10 IgG-binding proteins for direct visualization on Western blots
Pre-stained bands — 4 prestained proteins for monitoring protein separation during electrophoresis and Western blotting transferring efficiency on membrane
Wide range — 10 clear bands from 15 to 200 kDa for size estimation
Quick reference — two enhanced bands (30 and 80 kDa)
Contents
The YesBlot™ Western Marker I contains recombinant IgG binding proteins, prestained recombinant proteins, glycerol and SDS.
Storage
4°C for 3 months -20°C for 24 months

Brucella abortus is an intracellular, blood-borne parasite. It is a Gram-negative coccobacillus that causes an infectious and contagious disease called Brucellosis. The disease primarily affects cattle but it can also be transmitted to humans from infected animals and consuming their products. The disease can lead to great economic loss especially in the dairy and agricultural industry. The Brucella abortus genome contains two DNA chromosomes in a circular confirmation; the first chromosome is approximately 2.1 Mb and the second chromosome is approximately 1.2Mb. Unusually it does not contain any plasmids or genomic islands that relate to pathogenicity and lacks many other genes that code for common virulence factors including capsules, fimbriae, exotoxins, cytolysins, resistance forms, or antigenic variation. The most common mode of transmission to humans is through the ingestion of unpasteurized milk and cheese products as the bacteria are present in the milk glands of infected female cows. In cattle transmission can also be through ingestion but in addition, the bacteria can persist in the reproductive tracts of males, namely seminal vesicles, ampullae, testicles, and epididymides, allowing sexual transmission. In humans the bacteria enter macrophages by phagocytosis and then live in compartments of vacuolar space along the endoplasmic reticulum. They persist by inhibiting host apoptosis and go onto form chronic disease causing lesions in the liver, spleen, bone marrow and kidneys. In cattle the bacteria additionally infect the trophoblast epithelial cells, which provide nutrition to the embryo. The trophoblast cells eventually lyse, releasing further bacteria into the blood stream of the embryo. The B. abortus cells in the blood stream go on to colonize the placenta and fetus in pregnant female cows, resulting in abortion of the fetus. Abortion can also result from insufficient anti-Brucella activity in the amniotic fluid. In humans, the disease can be either acute or chronic and some of the symptoms include fluctuating fever, chills, sweating, headache, muscle pain and weight loss. Once a person becomes infected they are prescribed a combination of tetracycline and streptomycin for 3-6 weeks. In cattle, additional symptoms include arthritic joints and retained after-birth.

Magen’s HiPure columns are prepared by high quality glass fiber filter membrane as raw materials through membrane cutting, membrane release, ring release, ring pressing, gland, weighing and other processes. HiPure nucleic acid adsorption columns have the characteristics of long-term stability and high binding capacity. Experiments show that the highest binding capacity and binding efficiency of HiPure nucleic acid adsorption columns are basically unchanged when stored at room temperature for 4 years.
The series of nucleic acid columns produced by Magen Biotech are based on carefully selected imported glass fiber membranes (GF/B, GF/D, GF/F). Columns production processes such as polypropylene injection molding materials, injection molding process, and downstream membrane packing and compression rings are strictly controlled. This is to ensure that the column has extremely high adsorption capacity and long-term stability. Compared with conventional products on the market, Magen’s columns are with varieties, and binding rate will not change when stored at room temperature for 4 years.

Adsorption Mechanism
Based on the negatively charged DNA skeleton, it has a high affinity for positively charged glass fibers. In high salt and ethanol solutions, DNA/RNA binds to glass fiber and interacts with hydrophilic matrix on silica through hydrogen bond. DNA/RNA is tightly bound. All pollutants can be removed by washing solution. At high salt concentration, nucleic acids selectively bind to silicagel membrane, while other pollutants, mainly proteins, are removed by membrane washing.
