Recombinant CD19 Antibody (AF405) (Ab223516) - Flow Cytometry Flow cytometry analysis of CD19 expression by human peripheral blood lymphocytes (right panel) compared to an isotype control (left panel). Human peripheral blood cells were preincubated with Human Fc Receptor Blocking Solution (H1374078). The cells were then stained with Recombinant CD19 Antibody (AF405) (Ab223516) at 5μL/test for 1 hour at 4°C. Left panel - Mouse IgG (AF405) (Ab190076).

자주 묻는 질문
What does ExactAb? mean?
ExactAb? indicates the product has been validated for use in rigorous antibody validation workflows. Validation may include positive/negative control samples, signal-to-noise testing, and protocol-specific QC. Lot-specific test data is published on the Certificate of Analysis where available.
How should this product be stored?
Store at 2–8 °C, protected from light. Do not freeze. Freezing may cause irreversible damage to this material.
How is this product shipped?
This product ships chilled on wet ice. Unpack on arrival and transfer it to the storage condition stated above.
What does Recombinant mean?
Recombinant is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Recombinant is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
Which species reactivity has this antibody been validated against?
Validated reactivity is listed on the PDP and on each lot's datasheet. We validate against the most commonly tested species for the target (Recombinant CD19 Antibody (AF405)); cross-reactivity in untested species may exist but is not guaranteed. Contact technical support for specific species inquiries.
