Product Specific Information

For reconstitution, add 100 µL distilled water to obtain a final antibody concentration of approximately 1 mg/mL.
For conjugation experiments, perform an additional desalting step using Zeba Spin Desalting Columns (7K MWCO, 0.5 mL, Product #89882).

Target Information

The tumor suppressor protein p53 is a sequence-specific transcription factor activated by cellular stress. It mediates cell cycle arrest or apoptosis in response to DNA damage or nutrient deprivation. p53 up-regulates stress response genes such as p21waf1, leading to G1 or G2/M arrest.

Structural domains include:

• N-terminal transactivation domain
• Central DNA-binding domain
• Oligomerisation domain
• C-terminal regulatory domain

Phosphorylation at Ser15 is crucial for activation and stabilization, while Ser392 phosphorylation is associated with tumor formation. p53 plays roles in DNA repair, aging, oxidative stress, and neuronal functions such as long-term potentiation (LTP).
Mutations in the TP53 gene can lead to loss of tumor suppressor activity and are linked to various cancers and hereditary conditions like Li-Fraumeni syndrome.
