p27 Antibody / p27Kip1

• Catalog Number: orb248293
• Category: Antibodies
• Description: This antibody recognizes a 27kDa protein, identified as the p27Kip1, a cell cycle regulatory mitotic inhibitor. The p27Kip1 antibody is highly specific and shows no cross-reaction with other related mitotic inhibitors. p27Kip1 functions as a negative regulator of G1 progression and has been proposed to function as a possible mediator of TGF beta induced G1 arrest. It is a candidate tumor suppressor gene. This mAb is excellent for staining of formalin-fixed tissues.

• Hazard Information: This p27Kip1 antibody is available for research use only.
• Entrez: 1027
• Storage: Store the p27Kip1 antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
• Buffer/Preservatives: 0.2 mg/ml in 1X PBS with 0.1 mg/ml rAlbumin (US sourced) and 0.05% sodium azide
• Note: For research use only
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the p27Kip1 antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
• Expiration Date: 12 months from date of receipt.
