XPB Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

ERCC3 is a component of the core TFIIH basal transcription factor and functions as an ATP-dependent 3'-5' DNA helicase. ERCC3 is involved in nucleotide excision repair and is the cause of xeroderma pigmentosum complementation group B (XPB), also known as xeroderma pigmentosum II (XP2). Additionally, it has been found to be the cuase of Cockayne syndrome, and trichothiodystrophy (TTD). XPB is an autosomal recessive disease characterized by skin photosensitivity and a predisposition to skin cancer, and neurological abnormalities. Cockayne syndrome and TTD are similarly characterized by photosensitivity and neural abnormalities.
