Why does a particular point mutation serine to alanine lead to significant change in protein mobility on SDS-PAGE?

I made several point mutations on a protein, and found that only one particular Ser to Ala mutation leads to significant change in mobility of protein on SDS-PAGE (WB is attached). The drop in...

Covariate adjustment in SPSS

How can I perform covariate adjustment in SPSS (or AROC)? Seems that there are no guidelines, the only thing I can find are theoretical explanations which are not quite clear. Thank you in advance.

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...

James R Knaub

Looks like quite an exponential.

Not my area, but can you try repeating your experiment? At least six more data points would be nice. Maybe the sample size is too small, and/or maybe there was an instrument problem?

Miljan Markovic

James R Knaub We are probably gonna repeat our experiment one more time... But we did it two times already, and god quite similar data from it... The problem is the standard models wont fit the data, Im getting a "fit did not converge" reply for almost all the models I tried... And the ones that gave good results in the terms of the R2, the other parameters were enormously high or low... I dont know what to do, didnt encounter this kind of problem nowhere in literature...
