Rat IgM on Mouse Tissue
|From:||John Bliss <firstname.lastname@example.org>|
If you are trying to detect a rat IgM primary on mouse tissue, a very clean way
to go would be a Mouse x Rat IgM-biotin secondary antibody. Zymed just happens to
offer such a reagent (cat. no. 03-9840, clone: MARM-4). Please contact us if you
would like more details. Thanks.
