Yes, as long as you have modified the plasmid you received (i.e. cloned a cDNA into it, made coding mutations or otherwise modified its function such as changing the bacterial resistance, cloning method, mammalian selection or by adding a fusion tag).
If a researcher wanted to request this plasmid, he/she would write to you and not to whomever you received the original plasmid from. Therefore, your lab should submit this plasmid to the repository.
Please do not submit plasmids that have not been altered by your laboratory.
