What are the advantages of a recombinant monoclonal antibody?
This product is a recombinant monoclonal antibody, which offers several advantages including:

- High batch-to-batch consistency and reproducibility
- Improved sensitivity and specificity
- Long-term security of supply
- Animal-free batch production

For more information, read more on recombinant antibodies.

Conjugation ready
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

Sandwich ELISA
The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody in your assay.

P4HB is a protein known as Protein Disulfide Isomerase (PDI). It plays a significant role in catalyzing the formation of disulfide bonds. This protein helps to fold newly synthesized proteins by shuffling disulfide bonds. It has a molecular mass of around 57 kDa. P4HB is mainly expressed in the endoplasmic reticulum of cells. While its alternative name is ERp59 P4HB is integral to the protein folding machinery inside cells.

Biological function summary

P4HB functions in protein folding and assembly. By acting as a chaperone it protects proteins from misfolding and aggregation. P4HB operates as part of a larger multi-protein complex that assists in maintaining protein structure under stress conditions in the cell. Its activity ensures protein stability and proper cellular function important for cell viability and health.

Pathways

P4HB plays a central role in the unfolded protein response (UPR) and oxidative protein folding pathway. It interacts with proteins such as calnexin and calreticulin through its involvement in these pathways. During oxidative protein folding P4HB introduces disulfide bonds into nascent proteins while removing incorrect ones ensuring efficient protein quality control.

P4HB alteration has connections to diseases like cancer and neurodegenerative disorders. Its overexpression and activity can promote tumor growth by aiding cancerous cell survival through protein homeostasis. Moreover P4HB's association with amyloid precursor protein impacts the progression of Alzheimer's disease. These connections make P4HB a relevant target for research into therapeutic interventions.

Target data

This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins. Inside the cell, seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations and following phosphorylation by FAM20C, functions as a chaperone that inhibits aggregation of misfolded proteins (PubMed : 32149426). At low concentrations, facilitates aggregation (anti-chaperone activity). May be involved with other chaperones in the structural modification of the TG precursor in hormone biogenesis. Also acts as a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP. Receptor for LGALS9; the interaction retains P4HB at the cell surface of Th2 T helper cells, increasing disulfide reductase activity at the plasma membrane, altering the plasma membrane redox state and enhancing cell migration (PubMed : 21670307).
