General description

UNC84B (Protein UNC-84 homolog B or SUN2), is a single-pass nuclear envelope transmembrane protein responsible for nuclear migrations that are essential for development. UNC-84B has a predicted transmembrane domain and a C-terminal region with similarity to the S. pombe spindle pole body protein Sad1. UNC-84B interacts with RAB5A and is widely expressed, and highly expressed in the heart, lungs and muscles. UNC-84 may function to facilitate a nuclear-centrosomal interaction required for nuclear migration and anchorage.


Epitope: N-terminus

KLH-conjugated linear peptide corresponding to human Unc84B/SUN2 at and around the N-terminus.


This antibody recognizes Unc84B/SUN2 at the N-terminus.

Physical form

Affinity Purfied

Purified rabbit polyclonal in buffer containing 0.1 M Tris-Glycine (pH 7.4, 150 mM NaCl) with 0.05% sodium azide.

Storage and Stability

Stable for 1 year at 2-8°C from date of receipt.
