How to import multiple files in a for loop using sprintf or other

I'am trying to import text files which have similar names in which only a number changes:

node2_200.txt, node2_250.txt, node2_300.txt, and so on in increments of 50 (can be another amount)

what i tried was the following:

n = 9
A = 250
for i=1:n

     formatSpec = 'node2_%d.out';
     B1 = load(sprintf(formatSpec,A));
     A = A+50

end

The problem here is that the result for B1 is just the last iteration and I need a variable for each of the "n" iterations. In other words I need "n" arrays made up of each specific text file.

Any ideas??

B1{i} = load(sprintf(formatSpec,A));
