L = bwlabel(bw); %where bw is your binary image
bw2 = bw; %copy of binary image
bw2(L==5) = 0; %deletes the 5th object

Try my answer below. If that doesn't work, explain more in a new question, and attach your image. And say which blob you want to delete.

You can use ismember() to extract the ones you want.
newBinaryImage = ismember(labeledImage, listOfBlobsToKeep) > 0;
