HE4/WFDC2 Overexpression Lysate Summary

• Description:

  HE4/WFDC2 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC208491
  
  Accession#: NM_006103
  
  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: WFDC2

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: 10 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

This gene encodes a protein that is a member of the WFDC domain family. The WFDC domain, or WAP Signature motif, contains eight cysteines forming four disulfide bonds at the core of the protein, and functions as a protease inhibitor in many family members. This gene is expressed in pulmonary epithelial cells, and was also found to be expressed in some ovarian cancers. The encoded protein is a small secretory protein, which may be involved in sperm maturation.

FAQs for HE4/WFDC2 Lysate (NBL1-17841). (Showing 1 - 1 of 1 FAQ).

1. I would like to build a sandwich ELISA for detection of HE4 levels in human blood. I found there are several HE4 antibodies from your company. Could you please provide me some information among these products, which two antibodies will work well with the HE4 antigen in a sandwich ELISA pair?
   • At this time we have not tested any of our HE4 antibodies for use in a Sandwich ELISA. As such, we cannot say with certainty, which will work together as an effective pair. Often times in our experience, choosing a monoclonal antibody for capture, and a polyclonal antibody for detection will yield great results. If you plan on testing any of our HE4 antibodies for use in a Sandwich ELISA then we would encourage you to apply for our Innovators Reward Program. Under the terms of this program, you will be eligible for a full credit in exchange for your data, in the form of an online review, regardless of positive or negative results.
