IL-33 monoclonal antibody (Nessy-1) Immunohistochemistry
Figure: Immunohistochemical staining of endogenous human IL-33 in different human tissues (paraffin sections) using MAb to IL-33 (Nessy-1) (Prod. No. ALX-804-840). Method: Different human normal tissues (A: Stomach; B: Bronchus; C: Vulva/Anal skin; D: Nasopharynx) or cancer tissues (E: Colorectal cancer; F: Malignant glioma) were stained with MAb to lL-33 (Nessy-1) by standard immunohistochemistry.
