Description
Specificity:
Goat Anti-Human TROP-2 recognizes Human TROP-2. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
Background:
Trop-2 is a cell surface glycoprotein1 that is highly expressed in a wide variety of epithelial cancers. There is little or no expression of Trop-2 in adult somatic tissue.2 Trop-2 is a novel calcium signal transducer3 involved in the regulation of cell- cell adhesion.4 It is an oncogene that has potential as a therapeutic target.2 It is a possible candidate gene for diagnosis and molecular target therapy of colorectal cancer.5
Known Species Cross Reactivity: Hu+
Immunogen
Purified Recombinant Human TROP-2 (>98%)
Formulation
This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.
Reconstitution
We suggest aseptically reconstituting this biotinylated, lyophilized, antigen affinity purified polyclonal antibody with 1 ml of sterile 20 mM Trizma base, 0.15 M sodium chloride (1X Tris Buffered Saline) pH 7.2-7.3, containing 0.1% w/v bovine serum albumin (BSA). This will result in a final biotinylated antibody concentration of 50 µg/ml.
Storage and Stability
The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted bioin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.
Reported Applications
IHC (NBF/Par.), WB
IHC (NBF/Par.): This antibody should give satisfactory staining results when used at a concentration of 10 µg/ml. The recommended secondary antibody for IHC is UltraAvidin™- Horseradish Peroxidase (HRPO) (
Leinco Prod. No.: A106). For chromogenic detection with high signal and low background use 3, 3'-Diaminobenzidine Tetrahydrochloride (DAB) Substrate Kit (
Leinco Prod. No.: D100) or Optional Metal Enhanced DAB Substrate Kit (
Leinco Prod. No.: K107).
Western Blotting: To detect Human TROP-2 this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as UltraAvidin™- Horseradish Peroxidase (HRPO) (
Leinco Prod. No.: A106) and a chromogenic substrate such as TMB HRPO Membrane/IHC Substrate UltraSensitive™ One Component "Ready Use" (
Leinco Prod. No.: T343). The detection limit for Human TROP-2 is 5 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used.
Each investigator should determine their own optimal working dilution for specific applications.
