Syndecan-1/CD138 Overexpression Lysate Summary

• Description:

  Syndecan-1/CD138 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC217847
  
  Accession#: NM_001006946
  
  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: SDC1

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: 29.4 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

CD138, also known as Syndecan-1, is a transmembrane heparin sulfate proteoglycan that binds type I collagen. The relative molecular mass of CD138 is found to vary between 20-95 kDa due to the presence of a variable number of GAG modifications on each CD138 molecule. This protein appears to mediate binding of cells to the extracellular matrix. Among mature tissues, CD138 is expressed on simple and stratified epithelia, endothelial cells, and fibroblasts. (2,3) While stratified keratinocytes express CD138, their malignant transformation suppresses CD138 expression. Wound repair processes alter patterns of CD138 expression. Among hematopoietic cells, CD138 is expressed by immunoglobulin-negative pre-B cells in the bone marrow, immature B cells and by terminally differentiated plasma cells in lymphoid organs. CD138 expression has not been observed on mature, circulating peripheral B lymphocytes, however. (4-7) CD138 is also strongly expressed by multiple myeloma-derived cell lines and elevated levels of CD138 are present in the serum of patients with multiple myeloma, a negative prognostic indicator for the disease.
