EB1/EB2/EB3 (C-terminal region) (clone KT65), anti-human, mouse, rat

Background:
Microtubles (MTs) are oriented with a fast growing plus-end and a slower growing minus-end. The MT plus-end is a crucial site for the regulation of MT dynamics and MT association with different cellular organelles by several groups of plus-end tracking proteins (+TIPs). These +TIPs form comet-like accumulations at the plus ends of MTs to regulate MT dynamics and interactions. The +TIPs include diverse groups of proteins, such as motor and nonmotor proteins, MT polymerases and depolymerases as well as various regulatory and adaptor proteins. The End-Binding (EB) family of +TIPs includes EB1 (MAPRE1), EB2 (MAPRE2, RP1), and EB3 (MAPRE3, EBF3). EB proteins are ubiquitiously expressed +TIPs that can dimerize through a coiled-coil C-terminal region, and bind MTs through an N-terminal calponin homology domain. EB proteins can stabilize MTs, increase MT dynamics, and suppress MT pauses. These activities of EB proteins are important for mitotic spindle formatin and chromsome alighnment during mitosis, and may have important roles in the centrosome and cilia assembly.

Immunogen: Clone KT65 was generated from a GST fusion protein containing mouse EB1. This sequence is highly conserved in human and rat EB1.

Specificity: The antibody detects a 30 kDa* protein corresponding to the molecular mass of EB1 on SDS-PAGE immunoblots of human HeLa, mouse brain, and rat PC12 cells. The antibody also detects EB1 by immunocytochemistry in HeLa and A431 cells. The antibody may weakly detect endogenous EB2 and EB3 in some cells and tissues.

Buffer/Storage:
Rat monoclonal antibody purified with protein G chromatography is supplied in 100µl phosphate-buffered saline and 0.05% sodium azide. Aliquot and Store at –20°C. Stable for 1 year.
