Formaldehyde (IUPAC name methanal) is a chemical compound with the formula H2CO. Sources of formaldehyde in the home include building materials, smoking, household products, and the use of un-vented, fuel-burning appliances, like gas stoves or kerosene space heaters. Formaldehyde, by itself or in combination with other chemicals, serves a number of purposes in manufactured products. For example, it is used to add permanent-press qualities to clothing and draperies, as a component of glues and adhesives, and as a preservative in some paints and coating products.
What else can I help you with?
Does your car interior emit benzene?
probably when car is brand new, just like when you go into a fabric store like Hancocks or Cloth World, your eyes start running, if your sensitive to pernament press that is put in new fabric. Probably find acetone, formaldhyde too.But for the most part has all but left car after 90 days.
What are examples below is a chemical agent?
Chemicals which can be used as antimicrobial agents are: Alcohols: e.g. ethyl alcohol phenolic compounds: e.g. hexachlorophene Halogens: e.g. iodophor Heavy metals: e.g. silver nitrate Quaternary ammonium compounds: e.g. detergents- benzalkonium chloride and cetylpridospores., Zephiran Aldehydes: e.g. formaldhyde, glutaraldhyde ( 2% solution of glutaraldhyde is called cidex and is effective disinfactant GASES: e.g. ethylene oxid, betapropiolactone, vapourized hydrogen peroxide.
What is disadvantges of fluorescence microscopy?
Florence microscopy has 3 main different way to make the cell fluorescence each with the disadvantages. Label protein outside the cell and microinject it - Takes a long time for little results You can use Immunofloresence which is faster by direct or indirect. Indirect you get better results through more floresence and takes less time because you can order the antibodies off the internet. You can use GFP gene and insert it into the cell. What you can do is have a plasmid transfect it then the protein will glow - This has a downside if the protein doesnt fold. If you are doing the immunofloresence you need to prepare the cell. You need to kill it to use the antibodies. You use formaldhyde or gluteraldehyde or methanol for this. This will but everything in place (cytoplasm wont move) then use a detergent to punch holes in the membrane. Then you use your anti-bodies to go into the cell and attach to your primary proteins. that you want to see. To make these antibodies you can proceed either by monoclonal or polyclonal. inject the rabit or w/e animal with an antigen. You will get antibodies forming with the epitop to that antigen that antigen should be the protein you want. Polyclonal have more then 1 epitope. and you need the rabit to do this.. if it dies bye bye antibodies disadvantage Monoclonal have Hybridomas which are immortal cell lines, they regognize only 1 epitope. Myeloma cell with a lymophocytes. To make sure you only have there hybridoma cell you can put them in HAT which will kill the myloma cells and you only get hybridomas.
