Description

Background of Recombinant Anti-Mouse PD-1 Antibody (Clone: 29F.1A12.1)

The rat anti-mouse PD-1 monoclonal antibody (clone No. 29F.1A12.1, rat IgG2a kappa) reacts with the mouse PD-1 protein (CD279 or programmed death-1) encoded by the mouse Pdcd1 gene, a prominent immune checkpoint receptor belonging to the CD28 family of the Ig superfamily. PD-1 functions through downstream signaling pathways via its two B7-family ligands, PD-L1 and PD-L2. Extensive preclinical research demonstrates that in syngeneic mouse models of melanoma and other malignancies, T-cell mediated cytotoxicity can be reactivated and tumor growth can be transiently arrested via targeted anti-mouse PD-1 antibody treatment. The 29F.1A12.1 blocking antibody effectively inhibits the interaction between the PD-L1/PD-L2 proteins and their receptor PD-1 protein to restore anti-tumor immunity.

Our recombinant 29F.1A12.1 antibody is meticulously engineered with 100% precise amino acid sequences of the variable regions derived from the original rat hybridoma (clone: 29F.1A12), which was uniquely generated by immunizing rats with mouse PD-1 cDNA followed by the mouse PD-1-Ig fusion protein. Expressed in high-fidelity mammalian cells, this in vivo grade recombinant anti-mouse PD-1 antibody eliminates hybridoma gene drift, providing a high binding affinity <20 nM and purity >95%. Available in versatile recombinant formats including the classic rat IgG2a and the Fc-silent mouse IgG2c LALAPG (L234A/L235A/P329G) platforms, this ultra-pure, low endotoxin (<1 EU/mg), and azide-free formulation is fully cross-validated for Western Blot (WB), immunohistochemistry (IHC), Flow Cytometry (FC), and rigorous long-term in vivo functional assays.

Key Application: In vivo checkpoint blockade via intraperitoneal administration of anti-mouse PD-1 antibody (Syd Labs, Cat# PA007163.m2cLA) at 200 µg per injection (diluted in PBS to 2 mg/mL) to suppress metastatic melanoma tumor progression and evaluate synergistic physical therapy modulations in syngeneic murine models.

“In addition to the sham and LPT treatments, the mice were treated with anti-mouse programmed cell death protein 1 (PD1) antibody (#PA007163.m2cLA, Syd Labs) or an isotype control antibody (#PA007141, Syd Labs). Four treatments of 200 μg of antibody diluted in 100 μL of PBS (2 mg/mL) were administered intraperitoneally between days 9 and 21 of the experiment. The anti-PD1 dosing regimen of 200 ug per injection was selected based on established murine immunotherapy protocols rather than allometric scaling from human doses, consistent with prior studies demonstrating biological efficacy at this dose……”

Frequently Asked Questions (FAQ) about Recombinant Anti-Mouse PD-1 Antibody (Clone: 29F.1A12.1)

Q: What makes the recombinant 29F.1A12.1 clone distinct from other anti-mouse PD-1 antibodies?

(by AI) While multiple clones can block murine PD-1 pathways in vivo, clone 29F.1A12.1 stands out for its extensive multi-year publication record and its unique dual-compatibility in both functional assays and western blotting. (by Syd Labs) Our recombinant anti-mouse PD-1 antibody (clone 29F.1A12.1) is generated via genetic engineering from the original hybridoma (produced via non-traditional cDNA and protein immunization). This ensures unparalleled structural stability. Unlike other clones that are primarily restricted to in vivo usage, our recombinant 29F.1A12.1 is fully cross-validated for high-sensitivity Western Blot (WB), Flow Cytometry (FC), and immunohistochemistry (IHC), providing researchers with a seamless transition from protein expression verification to animal immunotherapy profiling.

Q: Which isotype and host species format of recombinant 29F.1A12.1 should I select for my syngeneic models?

Syd Labs offers the comprehensive matrix of recombinant 29F.1A12.1 formats to match specific host-engineered controls and eliminate non-specific Fc receptor activation:

1. Rat IgG2a (PA007163.r2a): The recombinant counterpart of the native hybridoma, offering a binding affinity <20 nM, ideal for standard checkpoint inhibition.
2. Mouse IgG2c / IgG2a LALAPG (PA007163.m2cLA / PA007163.m2aLA): Engineered with an Fc silent / Fc-silenced platform (L234A/L235A/P329G mutations). Select IgG2c LALAPG if you are using C57BL/6 or NOD mice, and IgG2a LALAPG for BALB/c strains to prevent ADCC-mediated target cell depletion and minimize anti-drug antibody (ADA) interferences.
3. Mouse IgG1-D265A (PA007163.m1DA): An alternative ultra-pure alternative for specialized effector-function silencing.
4. Rabbit IgG (PA007163.rt): A highly rare recombinant rabbit chimeric format, specifically built for advanced multiplexing panels or secondary staining controls where cross-reactivity with rat/mouse hosts must be strictly avoided.

Q: What is the in vivo half-life of recombinant 29F.1A12.1 and the recommended dosing protocol?

In standard syngeneic mouse models, the in vivo half-life of our recombinant Rat IgG2a (PA007163.r2a) and chimeric mIgG2c LALAPG (PA007163.m2cLA) formats is approximately 6 to 9 days. Because clone 29F.1A12.1 possesses an engineered binding affinity <20 nM, it delivers robust and predictable target saturation. For standard tumor models (such as B16-F10 melanoma or Lewis lung carcinoma), the established and published dosing regimen is 200 μg per injection diluted in PBS (2 mg/mL), administered via intraperitoneal (i.p.) injection every 3 to 4 days (twice a week) for a duration of 2 to 3 weeks, beginning around day 8–9 post-tumor inoculation.

Q: How do I pair the correct isotype control for the different engineered host formats of 29F.1A12.1?

Due to the extensive range of host frameworks available for our 29F.1A12.1 clone, matching the precise engineered negative control is a strict requirement to eliminate background artifacts:

• For the native Rat IgG2a variant (PA007163.r2a), pair with a standard recombinant Rat IgG2a isotype control.
• For the Fc-silenced Mouse IgG2c LALAPG format (PA007163.m2cLA) or Mouse IgG2a LALAPG format (PA007163.m2aLA), you must avoid wild-type controls; instead, explicitly pair them with an Fc-silent recombinant Mouse IgG2c/IgG2a LALAPG kappa isotype control (such as Syd Labs Cat# PA007141 series).
• For the unique Rabbit IgG format (PA007163.rt), ensure your control group receives a matching recombinant Rabbit IgG constant region control to properly baseline your multiplexed staining or in vitro assays.

Q: What are the purity, endotoxin standards, and storage conditions to prevent aggregation of recombinant 29F.1A12.1?

Every batch of our in vivo grade recombinant anti-mouse PD-1 antibody (clone 29F.1A12.1) undergoes stringent quality control. It is supplied as a 0.2 μM filtered solution in 1x PBS, completely azide-free and preservative-free to guarantee no cellular toxicity. The endotoxin level is certified to be less than 1 EU/mg (frequently <0.05 EU/mg for large-scale batches) via LAL assay, with a verified protein purity >95% via SDS-PAGE. To maintain long-term stability and prevent protein aggregation, store short-term at 2°C to 8°C (up to 1 month). For long-term storage up to 12 months, preserve in working aliquots at -20°C to -70°C in a manual defrost freezer. Strictly avoid repeated freeze-thaw cycles, which can induce physical fragmentation or precipitation.
