The Galectin family of proteins, with specificity for Nacetyllactosaminecontaining glycoproteins, consists of beta-galactoside binding lectins containing homologous carbohydrate recognition domains (CRDs). At least 14 mammalian galectins family members, which share structural similarities in their carbohydrate recognition domains (CRD), have been identified to date. Unlike the selectin family of proteins, the carbohydrate binding specificity of galectins is calcium-independent. A common function of galectins is to cross-link structures containing N-acetyl-lactosamine located at the cell surface and within the extracellular matrix. They also possess hemagglutination activity, which is attributable to their bivalent carbohydrate binding properties. Galectins are active both intracellularly and extracellularly. Although they are localized primarily in the cytoplasm and lack a classical signal peptide, galectins can also be secreted by one or more unidentified, non-classical, secretory pathways. They have diverse effects on many cellular functions including adhesion, migration, polarity, chemotaxis, proliferation, apoptosis, and differentiation. Galectins may therefore play a key role in many pathological states, including autoimmune diseases, allergic reactions, inflammation, tumor cell metastasis, atherosclerosis, and diabetic complications. The galectins have been classified into the prototype galectins(1, 2, 5, 7, 10, 11, 13, 14), which contain one CRD and exist either as a monomer or a noncovalent homodimer. The chimera galectins(Galectin3) containing one CRD linked to a nonlectin domain, and the tandemrepeat Galectins(4, 6, 8, 9, 12) consisting of two CRDs joined by a linker peptide.Galectins lack a classical signal peptide and can be localized to the cytosolic compartments where they have intracellular functions. However, via one or more as yet unidentified nonclassical secretory pathways, galectins can also be secreted to function extracellularly. Individual members of the galectin family have different tissue distribution profiles and exhibit subtle differences in their carbohydrate-binding specificities. Each family member may preferentially bind to a unique subset of cell surface glycoproteins.

The E.Z.N.A.® Blood RNA Kit is designed for the isolation of total intracellular RNA from up to 1 ml of fresh, or frozen whole blood treated with any common anticoagulant such as heparin, EDTA or acid-citrate-dextrose. The procedure completely removes contaminants and enzyme inhibitors making total RNA isolation fast, convenient and reliable. Red blood cells are selectively lysed and white cells are collected by centrifugation. After lysis of white blood cells under denaturing conditions that inactivate RNases, the lysate is homogenised with a homogeniser spin column. The sample is then applied to a HiBind® spin column. Cellular debris and other contaminants such as haemoglobin are effectively washed away and high-quality RNA is finally eluted in DEPC treated water.

The E.Z.N.A.® Plasmid Mini Kit I is designed to isolate up to 30 µg of high-quality plasmid DNA from 1 to 5 ml bacterial cultures in 30 minutes or less. Plasmid DNA purification is simplified with HiBind® Mini Column technology into three quick steps: Bind, wash, and elute. Purified plasmid DNA is immediately ready for a wide variety of downstream applications such as routine screening, restriction enzyme digestion, and manual/automated fluorescent DNA sequencing. E.Z.N.A.® Plasmid Mini Kit I is available in either V-spin or Q-spin column format. V-spin column formats have an attached lid while Q-spin columns do not. Both versions can be used for centrifugation or vacuum protocols.

Plasmid isolated with traditional purification procedures normally contain high levels of endotoxins (also known as lipopolysaccharides or LPS) that can significantly interfere with transfection experiments downstream. The E.Z.N.A.® Endo-Free plasmid mini kit II integrates an efficient endotoxin removal step into the plasmid purification procedure to produce high-quality transfection grade (<0,1 EU/µg) plasmid for efficient transfection. The bacterial cells are lysed using the alkaline-SDS lysis method. The cleared cell lysate is then treated with ETR reagent to efficiently remove the endotoxins. After adjusting the binding condition, the cell lysate is applied into the HiBind® DNA column and purified DNA is eluted from the column membrane.

Modified from the E.Z.N.A.® Plant RNA kit, the E.Z.N.A.® Fungal RNA kit uses an improved buffer system that is more efficient for fungal samples. This kit provides convenient and rapid methods for the isolation of total RNA from a variety of fungal species. Rather, the method involves a simple and rapid precipitation step for removal of much of the polysaccharides and phenolic compounds commonly found in fungal tissues. In combination with HiBind® RNA spin columns, this method permits purification of high quality RNA from as much as 200 mg tissue. The system is also efficient enough to purify total RNA from as little as 10 mg of tissue or 100 cells. Purified RNA can be used for many downstream applications such as RT-PCR, northern blotting, Poly(A)+ mRNA purification, and differential display.
