Transgenic lines, from left to right, are paired sets from lines containing all components but lacking the TNT receptor -LRB-- TNT receptor); lacking the chimeric histidine kinase -LRB-- Trg - PhoR); lacking the protein for nuclear translocation / transcriptional activation -LRB-- PhoB - VP64);
with the phospho - relay disrupted (PhoBD53A - VP64).
In addition, the presenter will provide guidance on experimental design for multiplexed antibody panels combining phenotypic markers
with phospho - specific intracellular targets, and discuss the use of fix and perm kits.
Western blot analyses
with phospho - specific antibodies suggested that stretching induces phosphorylation of ERK of the MAP kinase pathway, but did not induce phosphorylation of phosphatidylinositol 3 - kinase.

In these plants, there is no significant difference in the GUS activity
with or without the TNT ligand, indicating that the complete signal transduction system and

with immune phenotyping using surface markers is ideal.
Cell lysates were subjected to western blotting and sequentially probed
with Abs to phosphorylated p38 (

with loss of MEK1 and MEK2 (Fig 4A).
and affinity of antibody ACI - 5400 were characterized by a panel of methods: (i) measuring the selectivity for a specific
phospho - Tau epitope known to be associated
with tauopathy, (ii) performing a combination of peptide and protein binding assays, (iii) staining of brain sections from mouse preclinical tauopathy models and from human subjects representing six different tauopathies, and (iv) evaluating the selective binding to pathological epitopes on extracts from tauopathy brains in non-denaturing sandwich assays.
Furthermore, using a
