Answer:

This process can be performed using immunofluorescence analysis via antibodies.

Explanation:

<u>To test for the hypothesis</u>

To test for the hypothesis we have to analyze whether the neuronal phenotype is due to the binding of laminin to integrins, and this will enable us to determine which integrins are abundantly expressed on the neuronal cell membrane. This process can be performed using immunofluorescence analysis via antibodies

Finally when no differentiation markers are expressed in the laminin coated plates with mutant cells we can now say that it expresses integrins
