Trisodium citrate is a chemical compound with the molecular formula Na 3 C 6 H 5 O 7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart taste, and is a mild alkali.
A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solutions and salts of citric acid. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When citrate trianion is part of a salt, the formula of the citrate trianion is written as C 6 H 5 O 3− 7 or C 3 H 5 O ...
Trisodium phosphate (TSP) is an inorganic compound with the chemical formula Na 3 P O 4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent , builder , lubricant , food additive , stain remover , and degreaser .
Sodium citrate is used to prevent donated blood from clotting in storage, and can also be used as an additive for apheresis to prevent clots forming in the tubes of the machine. By binding with calcium ions in the blood it prevents the process of coagulation. It is also used as an anticoagulant for laboratory testing, in that blood samples are ...

In addition to their very good biodegradability, trisodium N-(1-carboxylatoethyl)iminodiacetate solutions are characterized by high chemical stability even at temperatures above 200 °C (under pressure) in a wide pH range between 2 and 14 as well as high complex stability compared to other complexing agents of the aminopolycarboxylate type.

In biochemistry and molecular biology, saline-sodium citrate (SSC) buffer is used as a hybridization buffer, to control stringency for washing steps in protocols for Southern blotting, in situ hybridization, DNA Microarray or Northern blotting. 20X SSC may be used to prevent drying of agarose gels during a vacuum transfer.
As such they have been banned in many countries, leading to the development of phosphorus-free agents, such as polycarboxylates (EDTA, NTA), citrates (trisodium citrate), silicates (sodium silicate), gluconic acid and polyacrylic acid; or ion exchange agents like zeolites. Alkali builders may also enhance performance by changing the pH of the wash.
