The low concentration does not significantly alter solution pH, ionic strength, or peptide folding in most applications
Figure 3c shows that surface-targeted LaccID enriches N-cadherin but not calreticulin, while surface-targeted APEX2 and HRP enrich both markers because of (1) substantial pools of APEX2 and HRP in the ER lumen because of their imperfect targeting to the cell surface, and (2) high activity of APEX2 and HRP in the ER compartment
Whether it is physical compression of the nerve root or a reduction in blood supply, symptoms include pain and numbness in either or both legs and back
We offer guidance on appropriate options, which may include lifestyle measures, nutritional support and, where suitable, supplemental NAD pathways
The focus is not just on treatment, but on helping people understand why a specific option fits their needs
