hnRNP A2B1 Overexpression Lysate Summary

• Description:

  hnRNP A2B1 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC219318
  
  Accession#: NM_002137
  
  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: HNRNPA2B1

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: 35.8 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

RNA polymerase II transcripts in the nucleus are in complex with several different proteins called heterogeneous nuclear ribonucleoproteins (hnRNPs). These proteins act in biological activities such as transcription, pre-mRNA processing, cytoplasmic mRNA ranslation, and turnover.2. hnRNPs can be isolated either by immunoprecipitation or by sucrose gradient fractionation of cell extracts. Isolated hnRNPs consist of protein groups named A to U and many of these protein groups consist of more than one isoform.3 The major steadystate proteins of the isolated hnRNP complex are the A1, A2, B1, B2, C1, and C2 with a range of molecular weights (34-43 kDa).3 hnRNP-A2/B1 proteins are located in the nucleus of most tissues cells; however, the hnRNP-A2 protein is found also in the cytoplasm of skin and esophagus cells. In rat brain, hnRNP-A2/B1 proteins are found in neurons in the cerebral cortices, hippocampal formation, olfactory regions, caudate-putamin, and the supraoptic ucleus of the hypothalamus.4 Expression of hnRNP-A2/B1 proteins was found also in lung development and its over expression correlated with lung cancer.5
