Specific proetins can be detected by its specific mono clonal antibody. Primary antibodies specifically binds to the proetins on the membrane. Secondary antibody interact with primary antibody and signals its presence by chemiluminescence.

What is blotting and types of blotting?
Blotting is a technique of transferring DNA or RNA or Protein from a gel to the membrane. nitrocellulose, PVDF or nylon membrane are used to attach these molecules permanently on them. Western, southern and norther blotting are the techniques used to transfer protein, DNA and RNA respectively. It is done to detect them with a specific probe or antibody. This can not be detected or easy to handle on the gel, so we do blot for these analysis.
What is western blot testing?
Western blot is an analytical method used to identify specific proteins on the sample. It is widely used in clinical labs to identify pathogens in the patient sample to conclude what disease it is. It is a powerful technique used in research labs.
What does a panceus do?
Panceu s is a stain that specifically stains proteins. In the western blot analysis after transfer step people usually stain the membrane to see wether proteins are transfered or not. It is reversable binding dye
Is it normal to get chunks of blood on your period?
Yes, those are small blot clots. Or so I was told.
Why is a blot clot inside an artery so dangerous?
A blood clot inside an artery can block the flow of blood, partially or entirely, which that artery would normally carry. If the artery supplies the heart and it becomes blocked, the result is a heart attack. If it supplies the brain and it becomes blocked, the result is a stroke. Either can easily be fatal, and if not fatal, can still be very damaging. And then, even if the artery supplies some other part of the body, every part of the body needs a blood supply, and there is going to be a problem if the blood supply is cut off or reduced.
What type of test is the western blot test?
Western Blots used to diagnose HIV infection detect antibody to a range of HIV proteins. Instead of giving just one answer, they show "positive" or "negative" for each protein on the western blot strip. This makes them very specific for HIV.
What is the theory behind western blotting?
A western blot is done by immobilizing cellular proteins on a thin membrane (usually PVDF or nitrocellulose) and detecting them with antibodies to specific proteins. Briefly, cells are lysed, proteins are resolved on a gel, then proteins are transferred to a membrane, and finally the proteins are detected by enzyme-conjugated antibodies.
What is western blot used for?
Western blot is used to detect any specific protein found in a sample. Normally tissue or cell lysates contain tons of different kind of proteins. By doing this analytical method one can identify the specific protein from the crude sample by antibodies.
Is western blot quantitative method?
Western blot can be semi-quantitative. This means that you cannot determine absolute protein levels, but you can detect differences between groups. For example, if you have 4 different samples, a western blot will be able to tell you which samples have the most of any specific cellular protein. Quantitation is usually perfomed using "densitometry software" such as NIH ImageJ.
What does it mean if HIV antibodies are detected by the western blot analysis?
It means that the person has HIV.
Character of a Western blot?
Western blotting is a technique to detect specific proteins from a sample such as cell or tissue lysates. Western blot is a membrane (nitrocellulose or PVDF) on which the proteins are transferred for further analysis. Proteins on the blot are visualized by specific antibodies.
The difference between IHC and western blot?
Immunohistochemistry (IHC) is a method used to visualize protein expression in tissue samples using antibodies and staining techniques, whereas western blot is a technique that detects and quantifies specific proteins in a sample using antibodies and gel electrophoresis. IHC is used to analyze protein expression in tissue samples, while western blot is used to analyze protein expression in cell or tissue lysates.

When is a western blot test performed?
If the EIA test is positive then the Western Blot Test is performed
In a northern blot What is detected using a nucleotide probe?
RNA
