CHMP4B, NT (CHMP4B, C20orf178, SHAX1, Charged multivesicular body protein 4b, Chromatin-modifying protein 4b, SNF7 homolog associated with Alix 1, SNF7-2, Vacuolar protein sorting-associated protein 32-2) (AP)

CHMP4B is a member of the chromatin-modifying protein/charged multivesicular body protein (CHMP) protein family. The protein is part of the endosomal sorting complex required for transport (ESCRT) complex III (ESCRT-III), which functions in the sorting of endocytosed cell-surface receptors into multivesicular endosomes. The ESCRT machinery also functions in the final abscisson stage of cytokinesis and in the budding of enveloped viruses such as HIV-1. The three proteins of the CHMP4 subfamily interact with programmed cell death 6 interacting protein (PDCD6IP, also known as ALIX), which also functions in the ESCRT pathway. The CHMP4 proteins assemble into membrane-attached 5-nm filaments that form circular scaffolds and promote or stabilize outward budding. These polymers are proposed to help generate the luminal vesicles of multivesicular bodies.\n\nApplications:\nSuitable for use in Western Blot, Immunohistochemistry, Flow Cytometry, ELISA\n\nRecommended Dilution:\nELISA: 1:1,000\nWestern Blot: 1:100-500\nImmunohistochemistry: 1:50-100\nFlow Cytometry: 1:10-50\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Do not freeze alkaline phosphatase conjugates which could result in a substantial loss of enzymatic activity. Light sensitive. Aliquots are stable for 6 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
