  Matched Tumor & Normal Tissue Lysate Set

  Diagnosis: Infiltrating ductal carcinoma
  
  Sex: Female
  
  Age: 54
  
  Grade: 2
  
  Stage: IIIB, T_4bN₁M₀
  
  Tumor Pathology Data
  
  Location: Left breast
  
  Gross findings: Tumor size 10 cm, ill demarcated. Ulceration of the skin. Cut section firm and white. Ipsilateral axillary lymph nodes examined: 2
  
  Microscopic Findings
  
  The tumor is composed of proliferation of malignant epithelial cells. The epithelial cells are arranged as groups which have invaded the stroma. The tumor cells have irregular, basophilic nuclei and abundant cytoplasm. Nuclear chromatin is coarse with prominent nuclei. Mitotic figures are evident. The stroma is infiltrated by small numbers of chronic inflammatory cells. Necroses are seen but blood vessel invasions are not revealed. The lymph nodes show metastasis (2/8).
  
  Preparation Method
  
  Tissue specimens are homogenized in modified RIPA buffer to obtain the soluble proteins, and centrifuged to clarify.
  Extraction 1: PBS, pH 7.4; 1 ug/ml Aprotinin; 1 mM NaF
  Modified RIPA Buffer: 1 mM EDTA; 1 ug/ml Pepstatin-A; 0.1% SDS; 0.25% Na deoxycholate; 1 ug/ml Leupeptin; 1 mM PMSF; 1 mM Na₃VO₄

Applications/Dilutions

• Application Notes: These lysates have not been subjected to denaturing or reducing conditions. This allows the tissue or cell lysate to be used in a variety of applications; to study protein-protein interaction, ligand binding, ELISA, immunoprecipitation, 1D and 2D gel electrophoresis, and Western blotting for the detection of specific protein targets.
  For use in 1D and 2D gel electrophoresis, the addition of a denaturing gel loading buffer with reducing agents may be required.
  Buffer requirements for performing protein-protein interaction and ligand binding studies can vary significantly from RIPA buffer and may require modifications. In most cases, tissue lysates in RIPA buffer can be used, directly in standard ELISA and immunoprecipitation assays.
  These lysates are proteomic discovery tools. Researchers should validate and optimize for individual use.

Packaging, Storage & Formulations

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