Code N°


BAS002-0.5: Basal Cell Marker Cocktail 2, p63 Protein + HMW Cytokeratin




Price: 400 € / 0.5 ml

Monoclonal Antibodies

Origin:Rabbit/Mouse
 
Isotype:IgG/IgG1
 
Clone:EPR5701/34ßE12
 
Format:liquid conc.
 
Quantity:0.5 ml
 
Working concentration:Dilution 1:25-1:50
 
Presentation:Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**.
 
Immunogen:Recombinant human p63 protein (aa 1-203) and cytokeratin extract of human stratum corneum
 
Specificity:nuclear p63 and cytoplasmic high molecular weight cytokeratins
 
Species Specificity:Human
 
General Information:The p63 protein, a homologue of the tumour-suppressor p53, is highly expressed in the nuclei of basal or progenitor layer of many epithelial tissues. p63 is detected in prostate basal cells in normal prostate glands and PIN. Other markers for basal cells are high molecular cytokeratins (CK 1, 5, 10 and 14), which can be labelled with HMW CK clone 34ßE12. In prostate adenocarcinoma basal cells disappear and staining with both p63 and HMW CK fails. Thus the combination of p63 and HMW CK is a useful tool as differential markers for benign prostate glands and adenocarcinoma (negative marker).
 
Positive control:Normal prostate tissue or skin
 
Pre-treatment:Use formalin-fixed and paraffin-embedded sections; Retrieval conditions: Unmasking fluid T, TEC buffer (Tris/EDTA/Citrate) pH 8 (Art. No. DE005) in a pressure cooker at 100°C 20-40 minutes.
 
Applications:IHC(P)
 
Incubation time:30-60 min
 
Secondary reagents:We recommend the use of BIOLOGO's Universal Staining System DAB (Art. No. DA005) or AEC (Art. No. AE005), but also other staining systems including anti-mouse and anti-rabbit IgG will be suitable.
 
Storage:2-8°C

Notes:
*BIOLOGO's antibodies are intended for in vitro research use only. They must not be used for clinical diagnostics and not for in vivo experiments in humans or animals.

** The preservative sodium azide is known to be poisonous and potentially hazardous to health. It should be handled only by trained staff. Despite of the product's low azide concentration it must be handled with care. Dispose according to regional rules!
