What is the purpose of deproteinization?
Deproteinization is Necessary for the Accurate Determination of Ammonia Levels by Glutamate Dehydrogenase Assay in Blood Plasma From Subjects With Liver Injury.
What are Deproteinization techniques?
The most popular methods found in the literature for serum deproteinization include precipitation of proteins with TCA (7–9), ACN (7, 9, 12, 20), or MeOH (14), and filtration and/or centrifugation with molecular weight cutoff filters (5, 6).
What is Deproteinization biochemistry?
the process of removing protein from a biological sample, either by precipitation of protein from solution or by hydrolysis of protein with proteolytic enzymes.
What is Deproteinizing agent in urea estimation in blood?
A simple method for determination of urea in blood and urine with diacetyl monoximeglucuronolactone reagent is presented. The stability of the color produced permits analysis of a large number of samples at one time. Deproteinization of blood is accomplished with sodium tungstate and alum.
How do you Demineralize chitin?
The results from the ICP-OES showed that treatment of P. segnis waste samples with 2 M of HCl at room temperature for 70 min with ratio of 1:20 (w/v) is the best process for demineralization of chitin.
Which reagent is used to determine urea nitrogen by Spectrophotometrically?
The reagent can also be used for determining urea. In this case the enzyme urease is used to catalyze the hydrolysis of urea into carbon dioxide and ammonia. The ammonia is then determined with Berthelot’s reagent….Berthelot’s reagent.

Is chitin and chitosan the same?
Chitin is the most abundant aminopolysaccharide polymer occurring in nature, and is the building material that gives strength to the exoskeletons of crustaceans, insects, and the cell walls of fungi. Through enzymatic or chemical deacetylation, chitin can be converted to its most well-known derivative, chitosan.
What is the source of chitin?
The main sources of raw material for the production of chitin are cuticles of various crustaceans, principally crabs and shrimps. In crustaceans or more specifically shellfish, chitin is found as a constituent of a complex network with proteins onto which calcium carbonate deposits to form the rigid shell.
What is the Berthelot method?
Berthelot’s reagent is an alkaline solution of phenol and hypochlorite, used in analytical chemistry. Ammonia reacts with Berthelot’s reagent to form a blue product which is used in a colorimetric method for determining ammonia. The reagent can also be used for determining urea.
Why is it called a dam?
Hydropower is often used in conjunction with dams to generate electricity. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.
What are the reference ranges for electrolytes in serum?
What are the reference ranges for Electrolytes? Type Range in mEq/L and mmol/L Sodium 135-145 mEq/L (milliEquivalents/liter) Potassium 3.5-5.0 mEq/L Chloride 98-108 mmol/L (millimoles per liter) Bicarbonate (Carbon Dioxide) 22-30 mmol/L
What kind of blood test is an electrolyte panel?
An electrolyte test or electrolyte panel is a blood test that helps to measure whether there is a deficit or imbalance of electrolytes in your body. An electrolyte test can also be done through a urine test. Does this test have any other names? – Electrolyte panel. – Lytes. – Sodium (Na). – Potassium (K). – Chloride (Cl). – Carbon dioxide (CO2).
What should I do if my electrolyte level is above normal?
If your electrolyte levels are above or below the normal levels, you must immediately consult your doctor who will explain the test results and start the treatment. Sodium or Na: Sodium is the most important component of your electrolytes and maintains the fluid and water retention in your body.
Which is the most important electrolyte in the body?
Sodium, potassium, and chloride are the significant electrolytes along with magnesium, calcium, phosphate, and bicarbonate … Electrolytes are essential for basic life functioning, such as maintaining electrical neutrality in cells, generating and conducting action potentials in the nerves and muscles.
