Description

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

The rat anti-mouse PD-1 monoclonal antibody (clone No. RMP1-14.1, rat IgG2a kappa) reacts with the mouse PD-1 protein (CD279 or programmed death-1) encoded by the mouse pdcd1 gene, a member of the CD28 family of the Ig superfamily. PD-1 has two ligands, PD-L1 and PD-L2, both of which belong to the B7 family. It has been shown that in mouse models of melanoma and colon cancer, tumor growth can be transiently arrested via anti-mouse PD-1 antibody treatment and anti-mouse PD-L1 antibody interventions which block the therapeutic interaction between the PD-L1 protein and its receptor PD-1 protein. The RMP1-14.1 blocking antibody effectively blocks the reciprocal binding of both the mouse PD-L1 protein and the mouse PD-L2 protein to the mouse PD-1 protein during in vivo checkpoints blocking.

Our recombinant RMP1-14.1 antibody is engineered with 100% precise amino acid sequences of the variable regions derived from the original rat hybridoma (clone: RMP1-14). Expressed in advanced mammalian cells, this in vivo grade recombinant anti-mouse PD-1 antibody delivers superior batch-to-batch consistency with a high binding affinity <2 nM and purity >95%. Available in versatile formats including the classic rat IgG2a and the Fc-silent mouse IgG2c LALAPG (L234A/L235A/P329G) platforms, this low endotoxin (<1 EU/mg), azide-free formulation eliminates non-specific cell activation, making it ideal for immunohistochemistry (IHC), Flow Cytometry (FC), in vitro neutralization, and long-term in vivo functional assays.

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

Q: What are the advantages of recombinant RMP1-14.1 antibody over hybridoma-derived versions?

(by AI) Traditional hybridoma-derived antibodies often suffer from hybridoma gene drift and batch-to-batch variability, which can compromise the reproducibility of long-term preclinical studies. (by Syd Labs) Our recombinant anti-mouse PD-1 antibody (clone RMP1-14.1) is engineered using 100% verified genetic sequences and expressed in advanced mammalian cell culture (CHO or HEK293 cells). This ensures absolute sequence integrity, exceptional batch reproducibility, and scalable production. Purified under rigorous quality controls, our in vivo grade recombinant RMP1-14.1 features high binding affinity <2 nM and a purity >95%, providing clean data without hybridoma-associated cellular contaminants.

Q: Which isotype or format of recombinant RMP1-14.1 antibody should I choose for my mouse model research?

Syd Labs provides versatile recombinant engineered formats of clone RMP1-14.1 tailored to specific mouse strains and biological applications to prevent immunogenicity and non-specific Fc interactions:

1. Rat IgG2a (PA007162.r2a): Features the classic variable and constant regions matching the original hybridoma. It is widely cited for standard, short-term in vivo checkpoint blockade.
2. Mouse IgG2c LALAPG (PA007162.m2cLA): This format utilizes a mouse constant region with LALAPG mutation (L234A/L235A/P329G) to create an Fc silent / Fc-silenced variant. Because inbred strains like C57BL/6, C57BL/10, and NOD express the IgG2c isotype rather than IgG2a, using the mIgG2c LALAPG format is highly recommended for these backgrounds during long-term or chronic administration to eliminate antibody-dependent cellular cytotoxicity (ADCC) and minimize anti-drug antibody (ADA) responses.

Q: What is the typical in vivo half-life of recombinant RMP1-14.1 and the recommended dosing frequency in mice?

In standard immunocompetent mice, the in vivo half-life of our recombinant Rat IgG2a (PA007162.r2a) and chimeric mIgG2c LALAPG (PA007162.m2cLA) formats ranges from 5 to 8 days, depending on the metabolic rate and tumor burden of the host. For established syngeneic murine tumor models (such as MC38 or CT26), the standard validated in vivo dosing regimen is 100 μg to 200 μg per mouse, administered via intraperitoneal (i.p.) injection every 3 to 4 days (twice a week). Treatment typically initiates once palpable subcutaneous tumors reach an average volume of 50–100 mm³ and continues for 3–4 weeks or until experimental endpoints.

Q: Which isotype control should be used alongside recombinant RMP1-14.1 to avoid experimental artifacts?

To secure reliable, publication-ready data from in vivo immune checkpoint blockades, your negative control must match the exact engineered backbone of your targeting antibody. If you are administering the native Rat IgG2a platform (PA007162.r2a), you must pair it with a recombinant Rat IgG2a isotype control. Crucially, if your study utilizes the Fc-silenced Mouse IgG2c LALAPG format (PA007162.m2cLA), using a wild-type control will invalidate your results due to background Fc-receptor activation differences; you must pair it with an Fc-silent recombinant Mouse IgG2c LALAPG kappa isotype control (such as Syd Labs Cat# PA007141 variants).

Q: What are the purity, endotoxin levels, valid applications, and storage guidelines for Syd Labs' recombinant RMP1-14.1?

Our in vivo grade recombinant anti-mouse PD-1 antibody (clone RMP1-14.1) is explicitly formulated for highly sensitive physiological environments. It is supplied as a 0.2 μM filtered solution in 1x PBS, entirely azide-free and preservative-free to ensure zero cytotoxicity. The endotoxin level is strictly maintained at less than 1 EU/mg of protein as determined by the LAL method. While optimized as a potent functional blocking agent in murine syngeneic tumor models, its exceptional specificity makes it fully cross-compatible with Flow Cytometry (FC), immunohistochemistry (IHC), and in vitro T-cell neutralization assays. For optimal stability, store at 2–8°C for short-term use (up to 1 month) or in working aliquots at -20°C to -70°C in a manual defrost freezer for up to 12 months, avoiding repeated freeze-thaw cycles to prevent protein aggregation.
