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.

 Struggling with One? Become a better singer in 30 days with these videos!

Is it getting better? 
Or do you feel the same? 
Will it make it easier on you now? 
You got someone to blame 
You say 

One love 
One life 
When it's one need 
In the night 
One love 
We get to share it 
Leaves you baby if you 
Don't care for it 

Did I disappoint you? 
Or leave a bad taste in your mouth? 
You act like you never had love 
And you want me to go without 
Well it's 

Too late 
Tonight 
To drag the past out into the light 
We're one, but we're not the same 
We get to 
Carry each other 
Carry each other 
One 

Have you come here for forgiveness? 
Have you come to raise the dead? 
Have you come here to play Jesus? 
To the lepers in your head 

Did I ask too much? 
More than a lot
You gave me nothing
Now it's all I got 
We're one 
But we're not the same 
Well we 
Hurt each other 
Then we do it again 
You say 
Love is a temple 
Love a higher law 
Love is a temple 
Love the higher law 
You ask me to enter 
But then you make me crawl 
And I can't be holding on 
To what you got 
When all you got is hurt 

One love 
One blood 
One life 
You got to do what you should 
One life 
With each other 
Sisters 
Brothers 
One life 
But we're not the same 
We get to 
Carry each other 
Carry each other
