Title: Laboratory Practicals : Qualitative Analysis Of Proteins
Course: Biochemistry > Section: Week 10- UNIT 4_3: Transcription

Purpose:

To detect the presence of peptides or proteins in a sample

Certain functional groups in proteins can react to produce characteristically colored products.

The color intensity of the product formed by a particular group varies among proteins in proportion to the number of reacting functional or free groups present and their accessibility to the reagent.

 The cells must be separated and burst before their DNA may be precipitated out of solution.

Over to you:

To detect the presence of peptides or proteins in a sample

Activity

Use the Biuret test
