Stomach Matched Tumor and Normal Tissue Lysate Summary

Description
1 x Human stomach tumor tissue lysate (1 mg/ml, 100 ug/vial)
1 x Human stomach normal tissue lysate (matched) (1 mg/ml, 100 ug/vial)

Matched Tumor & Normal Tissue Lysate Set

Diagnosis: Adenocarcinoma, poorly differentiated

Sex: Male

Age: 52

Grade: N/A

Stage: II, T3N0M0

Tumor Pathology Data


Location: Antrum

Gross findings: Ulcerative lesion located at the antrum, ill demarcated. Ulceration measures 4 cm in diameter. Cut section is firm and white.

Microscopic Findings

Tissue sections show proliferation of malignant cells. The epithelial cells have small, basophilic, irregular nuclei and abundant cytoplasm, Cytoplasm contains much mucin. Nuclear chromatin is coarse with prominent nuclei. Mitotic figures are not evident. The neoplastic cells form groups and lines invading the smooth muscle propria and serosa. The stroma is infiltrated by small numbers of lymphocytes, plasma cells, eosinophils and neutrophils. Blood vessel invasions are not revealed. Lymph nodes show hyperplasia.

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
