Description

Background of Recombinant Murinized Anti-Mouse PD-1 Antibody (Clone: RMP1-14.1)

The rat anti-mouse PD-1 monoclonal antibody (clone No. RMP1-14, rat IgG2a kappa) reacts with the mouse PD-1 protein (CD279 or programmed death-1) encoded by the mouse pdcd1 gene, a critical immune checkpoint receptor of the CD28 family. PD-1 interactions with its ligands, PD-L1 and PD-L2, negatively regulate T-cell activation. While traditional anti-mouse PD-1 therapeutic antibodies transiently arrest tumor growth in murine melanoma models, repeated administration of foreign rat-derived proteins often triggers significant anti-drug antibody (ADA) responses in mice, neutralizing biological efficacy during prolonged checkpoint blockade studies.

To overcome this limitation, our recombinant murinized anti-mouse PD-1 antibody (clone RMP1-14.1) represents the ultimate engineering format. It features not only the constant regions of the mouse IgG antibodies but also meticulously murinized variable regions derived from the original rat hybridoma (clone: RMP1-14). Expressed in high-fidelity mammalian cells, this in vivo grade recombinant murinized anti-mouse PD-1 antibody (Cat# PA007162.mm2cLA) combines the specificity of clone RMP1-14.1 with the Fc-silent mouse IgG2c LALAPG (L234A/L235A/P329G) platform. With a certified purity >95%, an ultra-low endotoxin level <1 EU/mg, and a completely azide-free 1x PBS formulation, this fully murinized variant delivers the lowest possible immunogenicity and zero Fc-mediated cytotoxicity, making it the premier choice for long-term chronic in vivo functional assays, Flow Cytometry (FC), and immunohistochemistry (IHC) in syngeneic mouse models.

We found that PD-1 expression was significantly increased in the hippocampus of chronic unpredictable mild stress (CUMS) mice. PD-1 deficiency or blockade of the PD-1/PD-L1 pathway with the RMP1-14 antibody improved depressive-like behaviors and cognitive deficits in CUMS mice. Furthermore, we demonstrated that the PD-1/PD-L1 pathway regulates neuronal excitability and synaptic plasticity in the hippocampus.

We show that PD-L1 is highly expressed on lymphatic endothelial cells (LECs) and its engagement by PD-1 on T cells regulates T cell migration. Blocking PD-1/PD-L1 interaction using RMP1-14 antibody in vivo increased T cell retention in lymph nodes. This mechanism provides a previously uncharacterized pathway for the regulation of T cell trafficking during immune responses.

We identified that macrophages are the main cells that interact with the Fc domain of anti-PD-1 antibodies. Interaction of the anti-PD-1 antibody (clone RMP1-14) Fc domain with macrophage Fc receptors impaired the antitumor activity of TLR9 agonists. Modifying the Fc domain to prevent this interaction restored the antitumor efficacy of the combination therapy.

Dual checkpoint blockade (anti-CTLA-4 and anti-PD-1) is highly effective but associated with significant immune-related adverse events. We investigated the role of IL-23 in the toxicity of dual checkpoint blockade. Treatment with RMP1-14 (anti-PD-1) and anti-CTLA-4 triggered severe colitis, which was prevented by prophylactic IL-23 blockade without compromising antitumor immunity.

Combining anti-angiogenic agents with immune checkpoint inhibitors has shown potential in cancer treatment. We evaluated whether pre-administration of an angiogenic inhibitor improves the efficacy of anti-PD-1 (RMP1-14) antibody treatment. The results indicated that normalized vascularization facilitated T cell infiltration and significantly enhanced the therapeutic outcomes of immunotherapy.

Frequently Asked Questions (FAQ) about Recombinant Murinized Anti-Mouse PD-1 Antibody (Clone: RMP1-14.1)

Q: What is the difference between a chimeric antibody and a fully murinized RMP1-14.1 antibody?

(by AI) Standard chimeric antibodies combine foreign rat variable regions with mouse constant regions, which can still trigger an immune response in recipient animals. (by Syd Labs) Our recombinant murinized anti-mouse PD-1 antibody (clone RMP1-14.1) represents a higher tier of genetic engineering. It features not only the mouse constant regions but also carefully murinized variable regions. By modifying the framework of the variable domain to mimic native mouse sequences while maintaining absolute antigen-binding specificity to murine PD-1 (CD279), this fully murinized format achieves the lowest possible immunogenicity for flawless translation in mouse models.

Q: Why should I use the murinized RMP1-14.1 antibody for long-term or chronic in vivo mouse studies?

During chronic or longitudinal animal studies lasting several weeks, repeated administration of traditional rat-derived or partially chimeric antibodies frequently triggers a robust anti-drug antibody (ADA) response in mice. These neutralizing host antibodies accelerate clearance and block the therapeutic interaction with the PD-1 protein, leading to premature experimental failure. Utilizing our recombinant murinized RMP1-14.1 antibody effectively avoids neutralizing ADA development, ensuring sustained systemic drug exposure and maximizing the physiological validity of long-term in vivo functional assays.

Q: What is the in vivo half-life of fully murinized RMP1-14.1, and what is the recommended dosing frequency?

Because our PA007162.mm2cLA contains murinized variable regions, it escapes rapid immune-mediated clearance commonly seen with rat IgG2a clones. In standard immunocompetent mice, the typical in vivo half-life of this fully murinized IgG2c platform spans approximately 7 to 10 days, which is significantly longer than raw hybridoma-derived versions. For standard syngeneic tumor models, we recommend a dosing schedule of 100 μg to 200 μg per mouse, administered intraperitoneally (i.p.) twice a week (every 3–4 days), starting when tumors reach an average volume of 50–100 mm³.

Q: Which isotype control should I use alongside the recombinant murinized anti-mouse PD-1 antibody?

To obtain reliable, publication-ready data from immune checkpoint blockades, your negative control must exhibit the exact same effector silencing mutations. For PA007162.mm2cLA (which features the mouse IgG2c LALAPG backbone), you must use a matching recombinant mouse IgG2c LALAPG kappa isotype control (such as Syd Labs Cat# PA007141 variants). Utilizing a non-mutated wild-type mouse IgG2a or IgG2c control will introduce experimental artifacts due to discrepancies in background Fc-receptor binding, invalidating your flow cytometry or tumor growth analysis.

Q: What are the specifications, strain compatibility, and storage conditions for catalog number PA007162.mm2cLA?

PA007162.mm2cLA is engineered with the mouse IgG2c LALAPG (L234A/L235A/P329G) kappa backbone, making it a perfect genetic match for C57BL/6, C57BL/10, and NOD mice backgrounds. The LALAPG mutation ensures the antibody is entirely silent / Fc-silenced, preventing unwanted ADCC or complement activation. Every lot features a purity >95% by SDS-PAGE and ultra-low endotoxin levels <1 EU/mg in a preservative-free 1x PBS matrix. For short-term usage, store at 2°C to 8°C for up to 1 month. For long-term stability up to 12 months, store in aliquots at -20°C to -70°C in a manual defrost freezer, strictly avoiding repeated freeze-thaw cycles to prevent protein aggregation.
