Mouse Monoclonal Antibody to Human WAP Four-Disulfide Core Domain 2

• Cat.No.: CAB11627MH
• Product Overview: Mouse Monoclonal Antibody to Human WAP Four-Disulfide Core Domain 2

Specification

• Antigen Description: WAP four-disulfide core domain protein 2, also known as Epididymal secretory protein E4, Major epididymis-specific protein E4, Putative protease inhibitor WAP5, WFDC2 and HE4, is a secreted protein which contains two WAP domains. WFDC2 / HE4 is a member of a family of stable 4-disulfide core proteins that are secreted at high levels. It is expressed in a number of normal tissues, including male reproductive system, regions of the respiratory tract and nasopharynx. It is highly expressed in a number of tumors cells lines, such ovarian, colon, breast, lung and renal cells lines. Initially described as being exclusively transcribed in the epididymis. WFDC2 may be a component of the innate immune defences of the lung, nasal and oral cavities and suggest that WFDC2 functions in concert with related WAP domain containing proteins in epithelial host defence. WFDC2 re-expression in lung carcinomas may prove to be associated with tumour type and should be studied in further detail. Mammary gland expression of tammar WFDC2 during the course of lactation showed WFDC2 was elevated during pregnancy, reduced in early lactation and absent in mid-late lactation. WFDC2 / HE4 can undergo a complex series of alternative splicing events that can potentially yield five distinct WAP domain containing protein isoforms.
• Specificity: Human WFDC2 / HE4. No cross-reactivity with human cell lysate ( 293 cell line ) in ELISA.
• Immunogen: Recombinant Human WFDC2 / HE4 Protein
• Host: Mouse
• Isotype: Mouse IgG2a
• Species: Human
• Clone: 6D3B6
• Applications: Western blot; ELISA
• Dilution: Western blot: This antibody can be used at 1-2 μg/mL with the appropriate secondary reagents to detect Human WFDC2 in WB. Using a DAB detection system, the detection limit for Human WFDC2 is approximately 8 ng/lane under non-reducing conditions. Use of this antibody under reducing conditions is not recommended.Direct ELISA: This antibody can be used at 0.5-1 μg with the appropriate secondary reagents to detect Human WFDC2. The detection limit for Human WFDC2 is approximately 0.0195 ng/well.
• Preparation: This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, human cell-derived, recombinant Human WFDC2 / HE4. The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
• Format: 0.2 μm filtered solution in PBS with 5% trehalose
• Storage: This antibody can be stored at 2-8°C for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20 to -70 °C. Preservative-Free.Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
