Hazel: Hi, everyone.
I'm super excited to say that I'm with Emilia,
Emilia: Hi.
Hazel: And Emilia is a science technician at Sancton Wood School in Cambridge.
And we're going to be doing some experiments together.
If you want to follow Emilia on Instagram, her handle is @emilia.science,
and she does some really cool experiments, so you should go check her out.
But I'm super excited because we're bringing Science with Hazel to the laboratory.
In this video, Emilia and I are going to show you how to test for protein.
It's a nice, straightforward test.
You simply need to use Biuret reagent.
Here's your sample.
This does contain protein.
Shake the two together.
And here, we can see the positive result forming,
which is that the solution has turned purple or mauve.
So to reiterate,
simply add your sample to Biuret reagent,
and protein gives off a positive result of a purple solution.
