<br><p>However, the expression level of HSP60 has been consistently concerning, and its content in the lysate supernatant is relatively low. The same situation happened to protein LAP as well. Both of the circumstances pose challenges for subsequent experiments like co-immunoprecipitation (Co-IP).</p>

<p>To determine whether the surface display protein, Neae, anchors on the outer membrane or not, we conducted a range of experiments. </p>
<br><p>Firstly, we employed indirect immunofluorescence(IF) to confirm the appearance of Neae. The result demonstrated that Neae presented a stronger fluorescence at 30℃(Fig. 21).</p>
