Description

Specificity:

Goat Anti-Human Beta-Site Amyloid Precursor Protein Cleaving Enzyme 1 (BACE-1) recognizes Human BACE-1. 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:

BACE-1 is an aspartic protease and an integral membrane protein. BACE-1 is the peptidase predominantly responsible for cleavage of the amyloid precursor protein β site in the brain to generate the amyloid β peptide. Because the amyloid β peptide is a major component of amyloid plaques, BACE-1 has been implicated in the onset and/or progression of Alzheimer's disease. BACE-1 is expressed in a variety of human tissues. It is likely that this peptidase has functions in addition to its hydrolysis of the amyloid precursor protein. The peptidase activity of BACE-1 is optimal under mildly acidic conditions (pH 3.5 -5.5), consistent with its proposed function in an acidic intracellular compartment.

Immunogen

NS0-Derived Recombinant Human BACE-1 Ectodomain

Formulation

This 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 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Reconstitution

We suggest aseptically reconstituting this lyophilized, antigen affinity purified polyclonal antibody with 1 µl of sterile 1X PBS pH 7.2-7.3. This will result in a final antibody concentration of 0.1 mg/ml.

Endotoxin

<0.1 EU/µg as determined by the LAL method

Storage and Stability

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, 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

Indirect ELISA, WB

Indirect ELISA: This antibody can be used in an indirect detection ELISA at 0.5 - 1.0 µg/ml with a suitable second step reagent such as Donkey Anti-Goat IgG (H&L)-Horseradish Peroxidase (Leinco Prod. No.: G505). The detection sensitivity of this indirect ELISA for Human BACE-1 is approximately 6 ng/well.

Western Blotting: To detect Human BACE-1 this polyclonal antibody can be used at a concentration of 0.1 - 0.2 µg/ml. This polyclonal antibody should be used in conjunction with compatible second-step reagents such as Donkey Anti-Goat IgG (H&L)-Horseradish Peroxidase (Leinco Prod. No.: G505) 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 BACE-1 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.
