Product Overview and Target Background

BACC1 Antibody (Aladdin SKU: Ab351163; supplier reference absea#OC-2477) is a research-grade antibody formulated in PBS (phosphate-buffered saline) without additional preservatives or carrier proteins. The PBS-only formulation provides flexibility for downstream conjugation, custom dilution, and compatibility with a broad range of assay buffers.

BACC1 (Beta-actin related protein 1 or as annotated in the source supplier catalog) is the intended protein target of this antibody. Researchers are advised to consult the full product datasheet supplied by Aladdin Scientific for confirmed species reactivity, immunogen sequence, host species, clonality, and isotype information prior to experimental design.

Note: Detailed molecular background information for BACC1 is not provided in the current source material. Researchers should cross-reference primary literature and the official datasheet for comprehensive target biology.

Formulation, Storage, and Handling Guidelines

Formulation: BACC1 Antibody (Ab351163) is supplied in PBS only. The absence of additives such as glycerol, BSA, or sodium azide means researchers should take extra care during handling to maintain antibody integrity.

Storage Recommendations: In the absence of specific datasheet guidance, standard best practices for PBS-formulated antibodies apply:

• Store at −20 °C for long-term preservation.
• For short-term use (up to 1–2 weeks), storage at 4 °C is generally acceptable.
• Avoid repeated freeze-thaw cycles, which can cause aggregation and loss of activity. Aliquot the antibody upon first thaw if repeated access is anticipated.
• Protect from light to preserve antigen-binding integrity.

Handling: Centrifuge the vial briefly before opening to collect contents at the bottom. Use low-protein-binding tubes and pipette tips to minimize antibody loss during dilution and transfer.

Always refer to the official product datasheet for lot-specific storage conditions and expiry information.

Recommended Application Protocols

While the specific validated applications for BACC1 Antibody (Ab351163) should be confirmed via the official datasheet, the following general protocol framework is provided for commonly used antibody applications. Researchers must perform empirical optimization for each application and sample type.

Western Blot (WB) — General Framework

1. Prepare cell or tissue lysates using an appropriate lysis buffer (e.g., RIPA buffer with protease inhibitors).
2. Separate proteins by SDS-PAGE and transfer to a PVDF or nitrocellulose membrane.
3. Block the membrane for 1 hour at room temperature using 5% non-fat dry milk or BSA in TBST.
4. Incubate with BACC1 Antibody at the manufacturer's recommended dilution overnight at 4 °C.
5. Wash 3× with TBST (10 minutes each), then incubate with appropriate HRP-conjugated secondary antibody for 1 hour at room temperature.
6. Detect signal using chemiluminescent substrate and image accordingly.

Immunofluorescence (IF) / Immunohistochemistry (IHC) — General Framework

1. Fix and permeabilize cells or tissue sections as appropriate for the target localization.
2. Block with 5–10% normal serum from the secondary antibody host species.
3. Apply BACC1 Antibody at optimized dilution; incubate overnight at 4 °C in a humidified chamber.
4. Wash and apply fluorophore- or enzyme-conjugated secondary antibody.
5. Counterstain nuclei (e.g., DAPI for IF) and mount for imaging.

Important: Always include appropriate positive and negative controls. Dilution ranges and incubation conditions must be optimized empirically for each laboratory's specific conditions.

Antibody Validation and Quality Assurance

Antibody validation is a critical step to ensure specificity and reproducibility of experimental results. For BACC1 Antibody (Ab351163), researchers are encouraged to apply the following validation strategies recommended by the broader scientific community:

• Genetic knockdown/knockout controls: Use BACC1 siRNA, shRNA, or CRISPR-Cas9 knockout cell lines to confirm that the antibody signal is abolished in the absence of the target protein.
• Overexpression controls: Verify antibody signal is enhanced in cells transfected with a BACC1 expression construct.
• Multiple antibody comparison: Corroborate findings with an orthogonal antibody recognizing a distinct epitope of BACC1.
• Peptide competition assay: Pre-incubation of the antibody with the immunizing peptide should block specific signal.
• Cross-reactivity assessment: Test in cell lines or tissues known to be BACC1-negative to confirm absence of non-specific binding.

Aladdin Scientific provides lot-specific quality control data where available. Researchers should request the Certificate of Analysis (CoA) for each lot purchased to review QC test results prior to use.
