Safety Considerations

The following safety precautions should be observed.

1. Use pipette aids to prevent ingestion and keep aerosols down to a minimum.

2. No eating, drinking or smoking while handling the stable line.

3. Wash hands after handling the stable line and before leaving the lab.

4. Decontaminate work surface with disinfectant or 70% ethanol before and after working with stable cells.

5. All waste should be considered hazardous.

6. Dispose of all liquid waste after each experiment and treat with bleach.

Q & A

Customer Reviews

The SQSTM1 gene encodes the p62 protein, which acts as a molecular bridge between the ubiquitin-proteasome system and the autophagy-lysosome pathway. Its structure includes self-oligomerization and binding domains for polyubiquitinated substrates. p62 is a key signaling hub, integrating nutrient sensing via the mTORC1 complex and oxidative stress sensing via Nrf2. Dysfunction of p62 is associated with neurodegenerative diseases and Paget''s bone disease. In cancer, p62 accumulation is frequently observed in autophagy-deficient tumors, contributing to genomic instability.

The human SQSTM1-stabilized cell line in the HCT 116 context is an ideal platform for investigating the role of selective autophagy in colorectal cancer and drug resistance. HCT 116 is a highly proliferative colon cancer cell line suitable for high-throughput applications. By overexpressing human SQSTM1, researchers can investigate how p62 levels affect the cells'' ability to respond to chemotherapy-induced proteotoxic stress. This cell product is widely used to screen for small molecules that can disrupt p62-ubiquitin interactions, a potential therapeutic strategy that could enhance the chemosensitivity of drug-resistant tumor cells.

High Quality

We utilized this HCT 116 line for our proteostasis research. Compared to transient transfection, this stable line from Creative Biogene provides a much more uniform signal across the population. The recovery after thawing was nearly 100%, which allowed us to start our experiments immediately.
