I set my own path to $PATH variable in BASH terminal to have global access to some of my scripts, but I can not access them in any directory

I used ~/.bash_profile to add new path to my $PATH variable. I added export PATH=”/usr/sbin:$PATH” to my ~/.bash_profile, then saved it, and typed source ~/.bash_profile in my terminal. I echo $PATH and I see that I have this path in my $PATH variable. But I cannot access lsof utility (this command is in /usr/sbin directory). Also I have this sutuation with any directories. I wanted to add a directory, I added it, I had this path in my $PATH variable, but I could not access scripts that I have there.
