BOB1 Overexpression Lysate Summary

• Description:

  BOB1 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC207562
  
  Accession#: NM_006235
  
  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: POU2AF1

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 (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: 27.3 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.

Packaging, Storage & Formulations

• Storage: Store at -80C. Avoid freeze-thaw cycles.
• Buffer: RIPA buffer

Lysate Details for Array

• Type: Overexpression

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

BOB1 is a novel 35kDa protein designated Bob1 (B cell Oct binding protein 1) is a lymphocyte specific transcription co activator protein. B cell specific transcription is mediated by octamer motifs found in immunoglobulin heavy and light chain gene promoters and in some immunoglobulin enhancers. These sites are bound by the B cell specific Oct1 and Oct2 transcription factors, and the B cell restricted co activator BOB.1/OBF.1. This protein interacts only with the Oct1/2 proteins through sub domains in the POU domain of the Oct1/2 proteins, enhancing their transcriptional efficacy. Although having no intrinsic capacity for DNA binding, Bob1 associates tightly with the octomer motif in the presence of Oct1 and Oct2. Bob1 is expressed at highest levels in spleen and peripheral blood leukocytes.
