Elisa

The enzyme-linked immunosorbent assay (ELISA) (, ) is a commonly used analytical biochemistry assay, first described by Eva Engvall and Peter Perlmann in 1971. The assay uses a solid-phase type of enzyme immunoassay (EIA) to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the protein to be measured. ELISA has been used as a diagnostic tool in medicine, plant pathology, and biotechnology, as well as a quality control check in various industries. In the most simple form of an ELISA, antigens from the sample to be tested are attached to a surface. Then, a matching antibody is applied over the surface so it can bind the antigen. This antibody is linked to an enzyme and then any unbound antibodies are remov… more »

Some things are hidden in weird lands 
Just like treasures 
Volcanic bombs sleeping in your belly
So innocently and you're their home
They're ready now,and a strong wind's blowing
On the way down
All seems to be bigger
And the way up 
It's a funny picture of me 
Loking like a monster
Up up upside down, oh 
Up up upside down, oh 
Up up upside down'so lost 
Up up up 

Upon the hill a friendly face showing up 
Lost in the woods you don't know who I am 
And all I want is to keep on swinging 
On my swing never felt so stable 
Though I'm small 
And I don't know many things 
But I just love you strangers 

Up up upside down, oh 
Up up upside down, oh 
Up up upside down, oh 
Upupup 

I have to lay down (it's like one thousand mouths talking to you) 
I have to lay down 
I have to lay down 
I have to lay down 

Up up upside down, so lost 
Up up upside down, so real 
Up up upside down, so lost 
Up up upside down, is all I am 
Up up upside down, is all I am 
I'm upupside down 
Up up upside down, I'm so lost 
It's so real 
Up up upside down is all I am
