General description

Nibrin (NBS1) is made up of 754 amino acids.


synthetic peptide corresponding to amino acids 735-753 of human NBS1 (nibrin), conjugated to KLH via an N-terminal added cysteine residue. The immunizing peptide differs from the rat and mouse corresponding sequences in two amino acids.

Physical form

Solution in 0.01 M phosphate buffered saline containing 15 mM sodium azide.
