LIMPII/SR-B2 Overexpression Lysate Summary

• Description:

  LIMPII/SR-B2 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC202162
  
  Accession#: NM_005506
  
  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: SCARB2

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: 54.1 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.

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

High density lipoproteins (HDLs) play a critical role in cholesterol metabolism and their plasma concentrations are inversely correlated with risk for atherosclerosis. SR-BI and SR-BII (previously known as SR-BI.2) are the alternatively spliced products of a single gene. SR-BII differs from SR-BI in that the encoded c-terminal cytoplasmic domain is almost completely different. SR-BII binds HDLs and mediates selective uptake of HDL cholesteryl ester, but with an approximately 4-fold lower efficiency than SR-BI. Nuclease protection assays show SR-BII to be abundant in mouse tissues expressing SR-BI, with SR-BII expression found in liver, adrenal glands, and testes. Although the role of SR-BII is not completely clear, research suggests that it may be a functional HDL receptor. In addition, SR-BII mRNA results from the alternative splicing of SR-BI precursor transcripts with the SR-BII isoform mediating selective transfer of lipid between HDL and cells. The relative expression and functional activities of these two isoforms create a potential means of regulating selective lipid transfer between HDL and cells.
