The practical guides for optimal design of binding experiments focused on obtaining proofs of protein self-association are suggested.
Independently, the fact of no additional layer thickness or adsorbed mass detected does not yet constitute sufficient proof for preventing secondary protein adsorption: for many systems, it is well known that adsorbed proteins are displaced by different species from solution [ 32] possibly resulting in a constant adsorbed mass but a change of adsorbate composition over time.
After biocatalytic successful proof-of-concept, future opportunities for protein engineering and process set-up appear.
Besides experimental proof for the existence of protein-DNA interaction, TFBS discovery algorithms have been developed to uncover conserved regions that might act as TFBSs (MEME [ 9], ARCS-Motif [ 10], GLAM2 [ 9], W-AlignACE [ 11], GIMSAN [ 12], RankMotif++ [ 13], GAME [ 14], and Tmod [ 15]).
A possible 3D structure was calculated for protein ABK24388.1 to provide proof of the sequence similarities.
Further proof for the functionality of this protein came from its proper location at the sarcolemma and the delivery of a gene encoding this 'minidysferlin' into a dysferlin-negative mouse model through an adeno-associated viral vector.
The migration of KCNE1 and KCNE3 with this large Kv12.2 channel complex is strong additional proof for specific interaction of these proteins in vivo and importantly shows that channel structure is maintained under the conditions we used for co-immunoprecipitation assays.
However, ortholog assignment is not necessarily proof for a function of the encoded proteins in the same process as the ancestral protein.
CAD proteins can be divided into 5 classes [ 35] with functional proof for the involvement of class 1 proteins in lignification.
Even though the occurrence of protein carbonyls is proof for oxidative stress, the measurement of those carbonyls is rather a general measure of an alteration of the cellular redox status.
While proof of principle has been given for production of retroviral vectors [ 20, 21] so far, a systematic approach evaluating RMCE for protein production has been missing.
