GRADE & PURITYCarrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.ExactAb™?ExactAb™ — Aladdin's antibody line emphasizing precision and validated quality. Use for reliable, specificity-validated antibody applications.Azide Free?Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory.Validated?Validated grade — performance confirmed in defined applications before release. Use when you want documented assurance the reagent works as stated.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.PBS Only?PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers.≥95%(SDS-PAGE)0.5 mg/mL
Ubiquitinated by MARCHF1 or MARCHF8 at Lys-244 leading to down-regulation of MHCII. When associated with ubiquitination of the beta chain at 'Lys-254', the down-regulation of MHCII may be highly effective.

Frequently Asked Questions
What is the purity of this product, and how is it determined?
This product is supplied at ≥95% purity, determined by SDS-PAGE. Lot-specific values are stated on the Certificate of Analysis.
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.
What does Carrier Free mean?
Carrier Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
How should this product be stored?
Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
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 (HLA-DR Mouse mAb); cross-reactivity in untested species may exist but is not guaranteed. Contact technical support for specific species inquiries.
