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.

You are not an enemy anymore
There's a ray of light upon your face now
I can look into your eyes
And I never thought it could be so simple

You can hear the music with no sounds
You can heal my heart without me knowing
I can cry in front of you
'Cause you're not afraid to face my weakness

When we'll wake up
Some morning rain will wash away our pain
When we'll wake up
Some morning rain will wash away our pain

'Cause it never began for us
It'll never end for us
'Cause it never began for us
It'll never end for us

You're not my enemy anymore
There's a ray of light upon your face now
It'll be all new again
There is something else
Just 'round the corner

So when we'll wake up
Some morning rain will wash away our pain
When we'll wake up
Some morning rain will wash away our pain

'Cause it never began for us
It'll never end for us
No it never began for us
It'll never end for us

I was looking for a place to stay
Are you looking for a place to stay?

No it never began for us
It'll never end for us
No it never began for us
It'll never end for us
No it never began for us
And it'll never end for us
