For WB: Use at a dillution of 1 to 2 μg/ml. Human lung tissue lysate can be used as a positive control and a band at 27 kDa can be detected. A lower band at 18 kDa was detected in human spleen, and mouse liver and kidney tissue lysates. Optimal concentrations/dilutions should be determined by the researcher.
Human lung tissue lysate. Also human spleen, mouse liver and kidney tissue lysates.
PBS, pH 7.2 with 0.02% sodium azide as preservative
Store as concentrated solution. Centrifuge briefly prior to opening vial. For short-term storage (1-2 weeks), store at 4ºC. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.

Apoptosis is related to many diseases and development. The p53 tumor-suppressor protein induces apoptosis through transcriptional activation of several genes. A novel p53 inducible gene was identified recently and designated p53DINP1 (for p53-dependent damage-inducible nuclear protein 1) and SIP (for stress induced protein) in human and mouse (1,2). A p53DINP1 antisense oligonucleotide inhibits and overexpression of p53DINP1 enhances Ser46 phosphorylation of p53, induction of p53AIP1, and cell death induced by DNA double-strand breaks (1). p53DINP1 may regulate p53-dependent apoptosis through phosphorylation at Ser46 and induction of p53AIP1. The p53DINP1/SIP gene encodes two proteins of 27 and 18 kDa in human and mouse termed p53DINP1-a and p53DINP1-b or SIP27 and SIP18 (1,2). p53DINP1/SIP is expressed in many tissues and induced by a variety of stress agents including UV stress, mutagenic stress, heat shock, and oxidative stress (2).
