BT-549 对照裂解物 (1 mg/mL)

Thermo Scientific BT-549 Control Lysate is a stimulated cell lysate that has been validated for the expression levels and phosphorylation of key targets in the TP53 signaling pathway.

BT-549 Control Lysate features include:
• Validated for the expression of TP53 and phosphorylated TP53 by western blotting and mass spectrometry analysis
• Optimized—stimulation and lysis conditions optimized for detection of TP53 signaling targets
• Convenient—lysate is ready-to-use for immunoprecipitation, immunoprecipitation to mass spectrometry, and western blotting applications
• Stable for two years at -80°C

The tumor suppressor protein TP53 functions as a negative checkpoint regulator for abnormal cell signaling, and can induce cell cycle arrest, activate DNA repair proteins, or initiate apoptosis. Mutations in TP53 often result abnormal cell growth and are commonly found in many types of cancer. This lysate has been validated for TP53 expression and phosphorylation.

The BT-549 cell line is a human triple negative epithelial breast cancer cell line derived from mammary gland. The BT-549 cell lysate is provided as frozen lysate at a standard concentration of 1 mg/mL (500 mg per vial). Lysates are prepared in non-denaturing buffer without loading dyes or dissociating agents (i.e., no 2-mercaptoethanol or dithiothreitol has been added). For western blot analysis, heat lysate to 95°C for 5 minutes. Add reducing agent before heating if desired. The recommended loading volume per lane is 10–20 μL (10–20 μg).
