Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol. 1 Application Abreviews IHC-Fr Notes Use at an assay dependent concentration. Target Function Potent tight-binding inhibitor of several G1 cyclin/CDK complexes (cyclin E-CDK2, cyclin D2CDK4, and cyclin A-CDK2) and, to lesser extent, of the mitotic cyclin B-CDC2. Negative regulator of cell proliferation. May play a role in maintenance of the non-proliferative state throughout life. Tissue specificity Expressed in the heart, brain, lung, skeletal muscle, kidney, pancreas and testis. High levels are seen in the placenta while low levels are seen in the liver. Involvement in disease Defects in CDKN1C are a cause of Beckwith-Wiedemann syndrome (BWS) [MIM:130650]. BWS is a genetically heterogeneous disorder characterized by anterior abdominal wall defects including exomphalos (omphalocele), pre- and postnatal overgrowth, and macroglossia. Additional less frequent complications include specific developmental defects and a predisposition to embryonal tumors. Note=Defects in CDKN1C are involved in tumor formation. Sequence similarities Belongs to the CDI family. Cellular localization Nucleus. Anti-p57 Kip2 antibody images Tissues were from mouse E14.5 wild-type embryonic heads fixed in neutral buffered formalin sectioned (5-7 um) horizontally through the eyes. Antigen retrieval (0.1M citrate buffer pH6.5) in a 1400W microwave (5 min high; 5 min low). Sections blocked in 0.4% BSA/5% goat serum in PBS for 1h. Antibody diluted (1:100) in block soln, applied overnight at 4C. Detection with anti-Rb Alexa green Ab (1:500), nuclear counterstain with Hoechst dye (bisbenzimide).

We do not have any further information relating to this image. 2 ab4058 staining mouse E14.5 embryonic eye tissue sections by IHC-Fr. Sections were PFA fixed and blocked with 1% BSA for 2 hours at 25°C prior to incubating with ab4058, diluted 1/100, for 12 hours at 25°C. A FITC conjugated goat anti-rabbit antibody, diluted 1/400 was used as the secondary. Immunohistochemistry (Frozen sections) - p57 Kip2 antibody (ab4058) This image is courtesy of an Abreview submitted by Dr Bing Lang ab4958 staining p57 Kip2 in non-transgenic mouse embryos by Immunohistochemistry (PFA fixed, paraffin embedded sections). Heads of mice were removed, fixed in 10% formalin, dehydrated, embedded in paraffin, sectioned (5-7 µm). Slides containing ocular sections from nonImmunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - p57 Kip2 antibody (ab4058) Image from Dr D Burgess et al, BMC Dev Biol. 2010 Jan 27;10:13, Fig 8. transgenic embryos were first deparaffinized and rehydrated. Antigens were retrieved by microwave treatment in 10 mM Sodium Citrate buffer (pH 6.0). Following antigen retrieval, the tissue sections were blocked with 10% normal horse serum for 30 minutes, at room temperature. The slides were then incubated with ab4058 at a 1/250 dilution overnight at 4°C. Following brief washes in PBS, the slides were incubated with the appropriate biotinylated-secondary antibodies for 30 minutes at 37°C. Antigenantibody complexes were then detected using streptavidin-linked Alexa 594 (red) at 1/1000 dilution. Sections were mounted using antifade media containing DAPI (blue). Images were captured using a Nikon Eclipse 3 Anti-p57 Kip2 antibody (ab4058) at 1 µg/ml + Skeletal Muscle (Human) Tissue Lysate adult normal tissue (ab29330) at 10 µg Secondary Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (HRP), pre-adsorbed at 1/3000 dilution developed using the ECL technique Performed under reducing conditions.
