Description

Background of Recombinant Anti-Mouse CD8a Monoclonal Antibody (Clone YTS 169.4)

The rat anti-mouse CD8a monoclonal antibody clone YTS 169.4 specifically reacts with the mouse CD8a protein—a T-cell surface glycoprotein encoded by the CD8A gene. As a critical component of the dimeric CD8 protein, CD8a is essential for cell-mediated immune defense and T-cell development. Beyond its physiological role, CD8A is recognized as a vital diagnostic and prognostic marker in inflammatory disorders and various tumor models.

Our in vivo grade recombinant anti-mouse CD8a monoclonal antibody (clone YTS 169.4) is engineered to provide superior performance over traditional hybridoma-derived products. By utilizing a low endotoxin production platform, we ensure that each batch meets stringent requirements for in vivo CD8+ T cell depletion assays. Our recombinant YTS 169.4 antibodies possess the complete amino acid sequences of the original hybridoma clone, guaranteeing high-fidelity binding, exceptional batch-to-batch consistency, and the reliability required for pristine, publication-ready research datasets.

Frequently Asked Questions (FAQ) about Recombinant Anti-Mouse CD8a Antibody (Clone: YTS 169.4)

Q: Can I use clone YTS 169.4 for in vivo CD8+ T cell depletion?

Yes, clone YTS 169.4 is highly effective for in vivo CD8+ T cell depletion in mouse models. Syd Labs provides a recombinant, sequence-defined, low-endotoxin version of clone YTS 169.4, engineered to ensure exceptional depletion efficiency with minimal non-specific immune activation.

Q: What is the difference between anti-mouse CD8a clone YTS 169.4 and clone 2.43?

While both clone YTS 169.4 and clone 2.43 target the mouse CD8α chain and can be utilized for in vivo CD8+ T cell depletion, they are derived from completely distinct hybridoma lineages. Researchers often select the YTS 169.4 clone to fulfill specific multi-color flow cytometry staining designs or when literature dictates this particular clone to avoid secondary cross-reactivity in specific animal protocols.

Q: What is the isotype and formulation of this recombinant YTS 169.4 antibody?

Syd Labs' recombinant YTS 169.4 antibody features the precise variable regions of the original rat hybridoma, expressed with a high-purity rat IgG2b kappa constant region (or its recombinant switch variants). It is formulated in 1x PBS, completely azide-free, and processed through our specialized low endotoxin platform to guarantee safety and efficacy in functional assays.

Q: Why choose recombinant YTS 169.4 over traditional hybridoma-derived antibodies?

Traditional hybridoma lines suffer from genetic drift and inherent batch-to-batch variation. Syd Labs' recombinant anti-mouse CD8a YTS 169.4 is produced in mammalian cells, ensuring absolute sequence consistency. This advanced platform guarantees ultra-low endotoxin levels (<1 EU/mg), eliminating the non-specific toxicity often associated with classic hybridoma formats and providing pristine, publication-ready research datasets.

Q: How do I verify CD8 depletion efficiency when using clone YTS 169.4?

The standard method is to perform Flow Cytometry analysis on peripheral blood or spleen cell suspensions 24-48 hours after injection. Important: To accurately quantify the remaining T cells without competitive interference from the depleting YTS 169.4 antibody, you must use a different non-competing anti-CD8a clone (such as clone 53-6.7) for your fluorescent staining protocols.
