Legend (4 ml) Each Legend (hyaluronate) Injectable Solution, 10 mg/ml, 4 ml vial Legend® (hyaluronate sodium) Injectable Solution is a clear, colorless solution of low viscosity. Legend Injectable Solution is pyrogen free, sterile acid biology chemistry in nucleic and does not contain a preservative. It is administered by intravenous or intra-articular injection. Hyaluronic acid, the conjugate acid of hyaluronate sodium, is extracted from the capsule of Streptococcus spp. acid biology chemistry in nucleic and purified, resulting in a form which is essentially free of protein acid biology chemistry in nucleic and nucleic acids. Legend Injectable Solution is supplied in 2 ml (20 mg) acid biology chemistry in nucleic and 4 ml (40 mg) vials. Each ml contains 10 mg hyaluronate sodium, 8.5 mg sodium chloride, 0.223 mg sodium phosphate dibasic acid biology chemistry in nucleic and 0.04 mg sodium phosphate monobasic. The pH is adjusted to between 6.5 acid biology chemistry in nucleic and 8.0 with sodium hydroxide or hydrochloric acid. Chemistry: Hyaluronic acid, a glycosaminoglycan, can exist in the following forms depending upon the chemical environment in which it is found: as the acid, hyaluronic acid; as the sodium salt, sodium hyaluronate (hyaluronate sodium); or as the hyaluronate anion. These terms may be used interchangeably but in all cases, reference is made to the glycosaminoglycan composed of repeating subunits of D-glucuronic acid acid biology chemistry in nucleic and N-acetyl-D-glucosamine linked together by glycosidic bonds. Since this product originates from a microbial source, there is no potential for contamination with dermatan or chondroitin sulfate or any other glycosaminoglycan. Pharmacology: Hyaluronic acid is a naturally occurring substance present in connective tissue, skin, vitreous humour acid biology chemistry in nucleic and the umbilical cord in all mammals. High concentrations of hyaluronic acid are also found in the synovial fluid. It also constitutes the major component of the capsule of certain microorganisms. The hyaluronic acid produced by bacteria is of the same structure acid biology chemistry in nucleic and configuration as that found in mammals. The actual mechanism of action for hyaluronate sodium in the healing of degenerative joint disease is not completely understood. One major function appears to be the regulation of normal cellular constituents. This effect decreases the impact of exudation, enzyme release acid biology chemistry in nucleic and subsequent degradation of joint integrity. Additionally, hyaluronate sodium exerts an anti-inflammatory action by inhibiting the movement of granulocytes acid biology chemistry in nucleic and macrophages. Hyaluronate molecules are long chains which form a filter network interspersed with normal cellular fluids. It is widely accepted that injection directly into the joint pouch enhances the healing of inflamed synovium by restoring lubrication of the joint fluid. This further supplements the visco-elastic properties of normal joint fluid. Contraindications: There are no known contraindications for the use of Legend® (hyaluronate sodium) Injectable Solution in horses. Toxicology: Legend Injectable Solution was administered to normal horses at one, three acid biology chemistry in nucleic and five times the recommended intra-articular dosage of 20 mg acid biology chemistry in nucleic and the intravenous dosage of 40 mg.

Red Sea Fish pHarm pH & Alkalinity Mini-Lab Test (100 Ph Tests; 60 Alkalinity Tests) 60 easy to use tests for accurate measurement of high range pH (7.4 - 8.6) acid biology chemistry in nucleic and alkalinity (buffer capacity). Includes liquid testing agents, easy to read color charts, test tube, instructions, acid biology chemistry in nucleic and buffer supplement.pH Indicator, 0.51 fl. oz.Alkalinity Indicator, 0.51 fl. oz.Buffer Supplement, 0.85 fl. oz.test tube with ml markings clearly marked acid biology chemistry in nucleic and stoppercolor scaleseasy to follow instructionsIntroduction To pH And AlkalinityThe pH is a very important parameter in the biology of aquatic organisms. It is a measure of the acidity or basicity of the water. The scale runs from zero to 14. Zero is the most acidic. Seven is neutral acid biology chemistry in nucleic and 14 is the most basic. The pH scale is not linear, but logarithmic. A change of one pH unit, for example from seven to six, means that the water gets ten times more acidic.Due to its chemistry, salt water is able to absorb a certain amount of acidic matter without a resulting change in pH. The substances in the water that do this are called buffers. The ability to withstand changes in pH is called buffer capacity. Based on a method of measuring buffer capacity, it is referred to as the alkalinity of seawater. In some of the literature alkalinity is termed "carbonate hardness" or "kh carbonate buffer". This is exactly the same measurement as is measured in the Alkalinity Mini-Lab test.pH And AlkalinityThe pH of natural sea water varies geographically in the world's oceans between 8.1 acid biology chemistry in nucleic and 8.4. On a local scale the pH is however remarkably stable. This is due to the dissolved buffers (mainly bicarbonates), which prevent pH changes. Because of the enormous volume of the ocean, a nearly inexhaustible stock of buffers are present. The sea can take up large amounts of acids without a noticeable change in pH.Compared to the sea the volume of a marine aquarium is very limited acid biology chemistry in nucleic and therefore the alkalinity is also limited. As fish produce acid waste products acid biology chemistry in nucleic and as the buffering substances are used up by calcareous algae acid biology chemistry in nucleic and invertebrates, the buffer capacity may become so low that the pH could suddenly fall. This would be very dangerous to all organisms in the aquarium.The alkalinity is measured in so called milli-equivalents of alkaline substances (for example sodium bicarbonate) per liter. These alkaline substances have the power to prevent pH drops. The alkalinity of natural sea water is approximately 2.5 milli-equivalents per liter. This level should also be maintained in the marine aquarium.A common symptom of an unsuitable pH is pH stress. Especially in the marine aquarium, unsuitable pH values are very stressful to fish, acid biology chemistry in nucleic and increase the chance of the fish being susceptible to disease (marine white spot). To maintain a correct acid biology chemistry in nucleic and stable pH, check the pH acid biology chemistry in nucleic and alkalinity weekly.

Sense (molecular biology) - Sense, when applied in a molecular biology context, is a general concept used to compare the polarity of nucleic acid molecules, particularly RNA, to other nucleic acid molecules. Depending on the context within molecular biology, sense may have slightly different meanings.
Directionality (molecular biology) - Directionality, in molecular biology, refers to the end-to-end chemical orientation of a single strand of nucleic acid. The chemical convention of naming carbon atoms in the nucleotide sugar-ring numerically gives rise to a 3' end and a 5' end.
Primer (molecular biology) - A primer is a nucleic acid strand, or a related molecule that serves as a starting point for DNA replication. A primer is required because most DNA polymerases, enzymes that catalyze the replication of DNA, cannot begin synthesizing a new DNA strand from scratch, but can only ...
Nucleic acid - A nucleic acid is a complex, high-molecular-weight biochemical macromolecule composed of nucleotide chains that convey genetic information. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
