ELISA(enzyme-linked immunosorbent assay) is a useful method for detecting the concentration of some compound, using the characteristic of specific binding between antigen-antibody. For macromolecular compounds,you can use SandwichELISA.To small molecule compounds,Competitive ELISA is suitable.Meretciel offer ELISA kits.
To test a compound, you can conduct various analytical techniques such as spectroscopy, chromatography, or mass spectrometry to determine its chemical structure and properties. Additionally, you can perform biological assays to assess its potential effects on living organisms.

What compound is responsible for beilstein test?
Chlorinated organic compounds are responsible for producing a positive Beilstein test. The production of a green flame during the test indicates the presence of halogens, such as chlorine, bromine, or iodine, in the compound. This test is commonly used to detect the presence of halogen atoms in organic compounds.
What compound are responsible for Beilstein test?
Compounds that contain halogens (chlorine, bromine, iodine) are responsible for producing a positive Beilstein test. The test detects the presence of halogens by forming a blue-green flame when the compound is heated with copper oxide in a flame.
Which halogens give a positive beilstein test?
Chlorine, bromine, and iodine give a positive Beilstein test. The test involves ignition of a compound in the presence of copper oxide, which forms a green flame due to the halogen present in the compound.
Why are the metals in a flame lab test used in a chloride compound instead of just by themselves?
Metals are used in a chloride compound in a flame test because the chloride compound helps to enhance the visibility of the colored flame. When the compound is heated in a flame, the metal ions in the compound absorb energy from the heat and emit light in specific colors, making it easier to identify the metal present.
Can a flame test be used to identify a non metal atom in a compound?
No, a flame test is typically used to identify the presence of certain metal atoms in a compound based on the characteristic colors they emit when heated. Non-metal atoms do not typically produce colored flames, so a flame test is not suitable for identifying non-metals in a compound.
What is the test for an ammonium compound?
To test for an ammonium compound, you can add sodium hydroxide solution to the compound and heat gently. If ammonia gas is produced, it confirms the presence of an ammonium compound.
How do you test if something is an element or a compound?
if it dissolves its a compound if not its an element.
Why lassaigne's test failure in diaso compound?
Lassaigne's test is based on the formation of a blue color when a compound containing a nitrogen atom is treated with sodium nitroprusside and sodium hydroxide. If a compound fails the Lassaigne's test for a diazo compound, it could be due to the absence of a nitrogen atom that can be converted to a diazonium salt, or the compound's structure may not be suitable for the reaction conditions required for the test to proceed.
Which compound gives positive Fehlings test?
Fehling test is used for reducing sugars.
What compound is responsible for beilstein test?
Chlorinated organic compounds are responsible for producing a positive Beilstein test. The production of a green flame during the test indicates the presence of halogens, such as chlorine, bromine, or iodine, in the compound. This test is commonly used to detect the presence of halogen atoms in organic compounds.
What is the compound formed in schweitzer's test?
The compound formed in Schweitzer's test is a greenish-blue complex called a ferrous tartrate complex. This complex is formed by the reaction between a ferrous salt (such as ferrous sulfate) and potassium ferricyanide in an alkaline solution.
In ring test of nitrate what chemical compound is formed?
This compound is an ironIII) penta aqua nitrosyl sulfate.
What compound are responsible for Beilstein test?
Compounds that contain halogens (chlorine, bromine, iodine) are responsible for producing a positive Beilstein test. The test detects the presence of halogens by forming a blue-green flame when the compound is heated with copper oxide in a flame.
How can you tell whether a compound reacts with bromine?
You can test if a compound reacts with bromine by adding bromine water to the compound. If the compound reacts with bromine, the characteristic reddish-brown color of the bromine water will fade as it reacts with the compound. This reaction is often used to test for the presence of unsaturated bonds in organic compounds.
What is an iki test?
It tests for the presence of starches in an organic compound..
Which halogens give a positive beilstein test?
Chlorine, bromine, and iodine give a positive Beilstein test. The test involves ignition of a compound in the presence of copper oxide, which forms a green flame due to the halogen present in the compound.
Why was homogenized rat liver added to the ames test?
The test compound is not necessarily the ultimate carcinogen. In many cases the resulting products in metabolism rather than the compound itself causes cancer. Say, you feed a lab animal with a test compound and it gets cancer. You analyze the animal and you will find that the initial compound is metabolized to other chemicals that directly caused cancer. So this is why a test compound need to be metabolically activated, that is, it has to be metabolized by body enzymes (rat liver has a lot!) and then added to Salmonella to see the mutagenicity.
