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.

Get back on the road 
Turn those headlights on
You know it's still dark
And a long way to your home
Come on don't give up
You've got to hold on
You'll know what to do if you'll know what you want

Go through these city lights
You don't recognize
Cause you don't belong here
You don't belong here
But here you found his heart

Fight for what you want
You got to take care
Look after your sisters your brothers
It's such a small world
They keep saying
It is such a small world
But it's enough to feel lost
And wander without love
Think without a heart
And survive without a soul

Go through these city lights
You don't recognize
Cause you don't belong here
You don't belong here
But here you found his heart
Here you found his soul
He gave you all his love
You'll never forgive yourself
You'll never forgive yourself
If you let him go
If you let him go
If you let him go
If you let him go
If you let him go
