1. Discovery and characterization of prolactin neutralizing monoclonal antibodies for the treatment of female-prevalent pain disorders
Stephanie Maciuba,et al.MAbs. 2023.PMCID: PMC10498814
“Prolactin (PRL) has recently been demonstrated to elicit female-selective nociceptor sensitization and increase pain-like behaviors in female animals. Here we report the discovery and characterization of first-in-class, humanized PRL neutralizing monoclonal antibodies (PRL mAbs). We obtained two potent and selective PRL mAbs, PL 200,031 and PL 200,039. PL 200,031 was engineered as human IgG1 whereas PL 200,039 was reformatted as human IgG4. Both mAbs have sub-nanomolar affinity for human PRL (hPRL) and produce concentration-dependent and complete inhibition of hPRL signaling at the hPRL receptor (hPRLR). These two PRL mAbs are selective for hPRL as they do not inhibit other hPRLR agonists such as human growth hormone or placental lactogen. They also cross-react with non-human primate PRL but not with rodent PRL. Further, both mAbs show long clearance half-lives after intravenous administration in FcRn-humanized mice. Consistent with their isotypes, these mAbs only differ in binding affinities to Fcγ receptors, as expected by design. Finally, PL 200,019, the murine parental mAb of PL 200,031 and PL 200,039, fully blocked stress-induced and PRL-dependent pain behaviors in female PRL-humanized mice, thereby providing in vivo preclinical proof-of-efficacy for PRL mAbs in mechanisms relevant to pain in females.”

背景知识

The recombinant human IgG2 isotype control （hIgG2 kappa isotype control antibody），（重组人IgG2同型对照抗体（hIgG2 kappa同型对照抗体））is produced in mammalian cells (HEK293 cells) like our other recombinant human IgG isotype control and mutant（重组人IgG同型对照抗体和突变体） antibodies. The ideal recombinant human IgG2 isotype control（重组人IgG2同型对照抗体） has low or no specific binding to any human sample, and humanized or completely human variable regions in addition to the human IgG2 kappa constant（人IgG2 kappa同型对照抗体） regions. The human IgG2 kappa isotype control（（人IgG2 kappa同型对照）） can be used in the cell-based assay or animal model as the antibody negative control.

Please contact us to ask for a quote for the hIgG2 isotype control（hIgG2同型对照抗体） with Avi-, His-, and Flag-tags. A variety of conjugates (such as biotin, dyes, and fluorophores) with the human IgG2 isotype control（人IgG2同型对照抗体） are available.

Naturally synthesized and secreted by plasma B cells, the immunoglobulin G (IgG) antibody（免疫球蛋白G抗体） is the most abundant antibody isotype found in blood and extracellular fluid. There are four IgG subclasses (IgG1, IgG2, IgG3, and IgG4) in humans, of which IgG1 is the most abundantnamed in serum. IgG antibodies are large molecules of about 150 kDa composed of four peptide chains, two identical heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The four peptides are arranged in a Y-shape tetramer by disulfide bonds formed between the two heavy chains and between a heavy chain and a light chain.

The arms of the Y, also called the Fab (fragment, antigen-binding) region containing an identical antigen binding site, is composed of one variable (located at amino terminal end, VH and VL) and one constant domain (CH1 and CL) from each heavy and light chain of the antibody. VH and VL, also called the FV region, is the most important region for binding to antigens. Three variable loops of β-strands, also called the complementarity determining regions (CDRs or idiotypes), on VH and VL respecetively are responsible for binding to the antigen.

The base of the Y, also called the Fc (Fragment, crystallizable) region and composed of two heavy chains with two or three constant domains depending on the class of the antibody, binds to a specific class of Fc receptors and other immune molecules, such as complement proteins, to induce an appropriate immune response for a given antigen. The Fc region bears two highly conserved N-glycosylation sites, one on each heavy chain. The N-glycans attached to this site are predominantly core-fucosylated diantennary structures of the complex type. In addition, small amounts of these N-glycans also bear bisecting GlcNAc and α-2,6-linked sialic acid residues.
