Cbx2 Overexpression Lysate Summary

Description

Cbx2 Transient Overexpression Lysate


Expression Host: HEK293T

Plasmid: RC216313

Accession#: NM_032647

Protein Tag: C-MYC/DDK

You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.
Gene
CBX2

Applications/Dilutions

Dilutions
  • Western Blot
Application Notes
This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (cat# NBP1-71705) present on the protein construct.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
Theoretical MW
23.1 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Notes

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.

Background

Polycomb' genes in Drosophila maintain the repressed state of homeotic and other developmentally regulatedgenes (Wedeen et al., 1986 (PubMed 3081265); Kuziora and McGinnis, 1988 (PubMed 2903050)) by mediating changes inhigher-order chromatin structure (Paro and Hogness, 1991 (PubMed 1898775)). M33, a mouse homolog of polycomb, wasisolated by means of the structural similarity of its chromodomain (Pearce et al., 1992 (PubMed 1352241)). The fifthexon of M33 contains a region of homology shared by Drosophila and Xenopus. In Drosophila, its deletion results in theloss of polycomb function.(supplied by OMIM)
