IAN12 Antibody

What is IAN12 Antibody and how does it differ from other immune-associated nucleotide antibodies?

IAN12 Antibody recognizes immune-associated nucleotide 12, which belongs to the family of immune-associated nucleotide-binding proteins. Unlike other antibodies in this family, IAN12 antibody targets specific epitopes within the nucleotide-binding domain structure. Similar to antibodies like DAP12 (TYROBP), IAN12 plays a role in immune signaling pathways, though with distinct binding characteristics and functional outcomes .

The methodological approach to distinguishing IAN12 from other related antibodies involves:

• Performing cross-reactivity analysis using western blot

• Conducting immunoprecipitation studies to identify unique binding partners

• Utilizing fluorometric analysis similar to those used with other antibodies to identify distinct binding profiles

What are the optimal storage and handling conditions for IAN12 antibody to maintain its functionality?

For maximum stability and functionality, IAN12 antibody requires careful handling similar to other research antibodies. Based on standard protocols for antibody preservation:

• Store at -20 to -70°C for long-term storage (up to 12 months from receipt date)

• For reconstituted antibodies, maintain at 2-8°C under sterile conditions for up to 1 month

• For extended storage after reconstitution, aliquot and store at -20 to -70°C for up to 6 months

• Avoid repeated freeze-thaw cycles which can significantly reduce antibody activity

How can researchers validate the specificity of IAN12 antibody before experimental applications?

Validating antibody specificity is crucial for experimental reliability. Methodological approaches include:

• Western blot validation: Run positive and negative control samples side-by-side to confirm specific binding to the target protein at the expected molecular weight

• Flow cytometry: Compare staining patterns between positive control cells (expressing IAN12) and negative control cells

• Competitive binding assays: Pre-incubate the antibody with purified antigen to demonstrate binding specificity

• Knockout/knockdown controls: Use genetically modified cells lacking the target protein to verify absence of signal

What are the optimal dilution ranges for IAN12 antibody across different applications?

Determining optimal antibody dilutions requires systematic titration experiments for each application:

Each laboratory should determine optimal dilutions experimentally, as factors including antibody lot, sample preparation, and detection systems influence performance. Establishing a standardized protocol through systematic testing is essential for reproducible results .

How can researchers effectively design experiments to distinguish between specific and non-specific binding of IAN12 antibody?

Designing experiments to distinguish specific from non-specific binding requires multiple controls and validation approaches:
