Custom Mouse Monoclonal Antibody Services (Mice 🐁)

LifeTein provides custom mouse monoclonal antibody services for peptide antigens, phosphopeptides, and recombinant protein immunogens. The standard mouse monoclonal workflow, typically involves immunization, fusion or clone-generation workflow, screening, subcloning, purification, and isotype determination.

Mouse monoclonal antibodies remain a practical choice for many research applications, especially when researchers want a conventional monoclonal workflow or have an assay history that already fits mouse antibodies well.

When to Choose Mouse mAb vs Rabbit mAb

• Choose mouse mAb when you want a conventional monoclonal workflow or need compatibility with an established assay format
• Choose rabbit mAb when higher affinity or more difficult epitopes are a major concern
• Choose peptide polyclonal service when speed, broader recognition of a designed peptide region, and peptide affinity purification are the highest priorities

LifeTein generated Anti-gM and anti-gN antibodies for Vaccine Analytical Research Development and Vaccine Process Development Merck & Co., Inc., Kenilworth, NJ, USA. The rabbit polyclonal anti-gM and anti-gN antibodies were elicited by vaccinating animals with synthesized peptide sequences of gM (1-13aa and 345-372aa) and gN (61-101aa). Animal immunization and sera collection were performed at Lifetein, LLC (Hillsborough, NJ, USA). The sera were affinity-purified by its corresponding peptides.

LifeTein helped designed and synthesized a series of phosphorylated peptides. Then the peptides were used for phospho-specific antibody productions. The phospo-specific antibodies by LifeTein were confirmed to react with the epidermal growth factor receptor (EGFR). The Hung's lab showed that AGO2-Y393 phosphorylation mediates EGFR-enhanced cell survival and invasiveness under hypoxia. These findings suggest that modulation of miRNA biogenesis is important for stress response in tumour cells.

Custom peptide antibodies were provided by LifeTein to study SKPO-1. The SKPO-1 peroxidase domain peptide was synthesized by LifeTein. The polyclonal antibodies were raised in rabbits and then affinity purified to accomplish high specifications and concentrations. The antibodies were successfully used to localize the SKPO-1 protein in hypodermis. It was found that the peroxidase SKPO-1 contributes to the host immune response during infection.
