Anti-Mouse PD-1 Monoclonal Antibodies

Background of Anti-Mouse PD-1 Monoclonal Antibody (29F.1A12)

The rat anti-mouse PD-1 monoclonal antibody 29F.1A12  (rat IgG2a kappa) reacts with the mouse PD-1 protein (programmed death-1 or CD279) 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, tumor growth can be transiently arrested via treatment with the anti-mouse PD-1 and anti-mouse PD-L1 antibodies which block the interaction between the PD-L1 protein and its receptor PD-1 protein. The 29F.1A12 monoclonal antibody blocks the binding of both the mouse PD-L1 protein and the mouse PD-L2 protein to the mouse PD-1 protein.

Our recombinant 29F.1A12 antibodies have a part (variable regions) or complete amino acid sequences of the rat anti-mouse PD-1 monoclonal antibody (hybridoma clone name or number: 29F.1A12).

“The experimental design of the four in vivo experiments reported in this study is shown in …… 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 ?g of antibody diluted in 100 ?L 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 [21, 22]. Mice were divided into four treatment groups: group 1 received sham treatment and isotype control antibodies; group 2 received LPT and isotype control antibodies; group 3 received sham treatment and anti-PD1 antibodies; and group 4 received LPT treatment and anti-PD1 antibodies. The cancer cells were injected on experimental day 0, treatments started on day 8, ended on day 22, and the mice were euthanized with carbon dioxide inhalation and on day 25.”

Questions and Answers about anti-mouse PD-1 antibody (Clone 29F.1A12):

Question: Which anti-mouse PD1 antibody works the best?
Answer: (by AI) There are several anti-mouse PD1 antibodies available in the market. Bio X Cell offers three different anti-mouse PD-1 monoclonal antibodies: Clones RMP1-14, 29F.1A12, and J43. All three of these antibodies are commonly used to block PD-1 signaling in vivo in murine tumor models and other mouse models. These three clones all have extensive multi-year publication records supporting them. Leinco Technologies offers four different anti-PD-1 monoclonal antibodies: 29F.1A12, RMP1-14, J43, and 5C4-B83. The RMP1-14 antibody has been reported to block the binding of PD-1 to its ligands (B7-H1 and B7-DC) and to inhibit T cell proliferation and cytokine production costimulated by macrophages (but not by dendritic cells and B cells). (by Syd Labs) Syd Labs offers anti-mouse PD-1 / CD279 monoclonal antibodies based on the sequences of clones RMP1-14 and 29F.1A12. Syd Labs provides in vivo grade recombinant antibodies including engineered antibodies for the clones RMP1-14 and 29F.1A12.

Question: Do you produce Fc-silenced 29F.1A12 antibody?
Answer: We provide recombinant 29F.1A12 antibodies including the Fc-silenced or Fc silent versions of recombinant 29F.1A12 antibodies. It is very easy for us to produce the Fc-silenced or Fc silent versions of recombinant 29F.1A12 antibodies no matter which isotypes they are based, for example, mIgG2c LALAPG.

Question: What are the published applications of the 29F.1A12 antibody?
Answer: It was reported that the blockade of the PD-1 protein expressed on TME-infiltrating macrophages and natural killer (NK) cells by 29F.1A12 results in tumor growth suppression and prolonged survival. It is also reported that the 29F.1A12 antibody recognizes the PD-1 surface protein on B16-F10 and other murine tumor lines, suppresses cancer cell-intrinsic PD-1 receptor signaling, and inhibits resultant tumor growth in three-dimensional (3D) culture and tumor-bearing mice. In the paper "Distinct antibody clones detect PD-1 checkpoint expression and block PD-L1 interactions on live murine melanoma cells", it was shown that the anti-PD-1 29F.1A12 monoclonal antibody recognizes the PD-1 surface protein on live B16-F10 melanoma cells, live YUMM melanoma variant lines, and overlapping WT murine B16-F10 and YUMM melanoma and T-cell subsets by FACS. In contrast to the RMP1-30 antibody, The 29F.1A12 PD-1 blocking antibody inhibits PD-1 interactions with PD-L1 on live B16-F10 melanoma cells. The RMP1-14 clone, but not 29F.1A12 or RMP1-30, is useful for pulling down (IP) and sequencing PD-1 from B16-F10 and T-cell cultures, consistent with the previous observations that individual antibodies differ in their suitability for specific assay types. 29F.1A12 binding to B16-F10 cells was increased in 3D versus 2D settings.
