Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue sections labeling Clusterin with purified ab92548 at 1/450 dilution (0.23 μg/ml). Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer pH 9.0). ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Negative control : PBS instead of the primary antibody. Hematoxylin was used as a counterstain. This data was developed using the same antibody clone in a different buffer formulation containing PBS BSA glycerol and sodium azide (ab92548)

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.

What does low endotoxin mean?
Our low endotoxin, azide-free formats have low endotoxin level (1 EU/mg, determined by the TAL assay) and are free from azide, to achieve consistent experimental results in functional assays.

Supplementary information

Clusterin also known as Apolipoprotein J (ApoJ) is a glycoprotein with a mass of approximately 75-80 kDa. Scientists find clusterin expressed widely in the human body including the brain kidney and reproductive organs. This protein exists in two isoforms a secreted form and a nuclear form each with different locations and functions within the cells.
Biological function summary

Clusterin plays multiple roles particularly in lipid transport apoptosis and cell-cell interactions. It does not form part of a larger protein complex but it acts as a molecular chaperone that helps in folding and clearance of damaged proteins. This capability allows clusterin to protect cells against stress conditions such as oxidative stress by preventing abnormal protein aggregation.

Pathways

Clusterin is involved in pathways related to cell survival and lipid metabolism. It plays a role in the insulin signaling pathway and interacts with proteins like Heat Shock Protein 70 (HSP70) to assist in protein folding and in the activation of apoptotic pathways when needed. Clusterin's function in these processes helps in maintaining cellular homeostasis.

Scientists associate clusterin with Alzheimer’s disease and cancer progression. Elevated levels of clusterin have been observed in Alzheimer's patients suggesting a role in amyloid-beta plaque formation. In cancer clusterin expression influences tumor progression and resistance to therapies. Its interaction with other proteins such as Bax modulates the apoptotic pathways impacting cancer cell survival and chemotherapy resistance.

Target data

Isoform 1. Functions as extracellular chaperone that prevents aggregation of non native proteins (PubMed : 11123922, PubMed : 19535339). Prevents stress-induced aggregation of blood plasma proteins (PubMed : 11123922, PubMed : 12176985, PubMed : 17260971, PubMed : 19996109). Inhibits formation of amyloid fibrils by APP, APOC2, B2M, CALCA, CSN3, SNCA and aggregation-prone LYZ variants (in vitro) (PubMed : 12047389, PubMed : 17407782, PubMed : 17412999). Does not require ATP (PubMed : 11123922). Maintains partially unfolded proteins in a state appropriate for subsequent refolding by other chaperones, such as HSPA8/HSC70 (PubMed : 11123922). Does not refold proteins by itself (PubMed : 11123922). Binding to cell surface receptors triggers internalization of the chaperone-client complex and subsequent lysosomal or proteasomal degradation (PubMed : 21505792). Protects cells against apoptosis and against cytolysis by complement (PubMed : 2780565). Intracellular forms interact with ubiquitin and SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes and promote the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed : 20068069). Promotes proteasomal degradation of COMMD1 and IKBKB (PubMed : 20068069). Modulates NF-kappa-B transcriptional activity (PubMed : 12882985). A mitochondrial form suppresses BAX-dependent release of cytochrome c into the cytoplasm and inhibit apoptosis (PubMed : 16113678, PubMed : 17689225). Plays a role in the regulation of cell proliferation (PubMed : 19137541). An intracellular form suppresses stress-induced apoptosis by stabilizing mitochondrial membrane integrity through interaction with HSPA5 (PubMed : 22689054). Secreted form does not affect caspase or BAX-mediated intrinsic apoptosis and TNF-induced NF-kappa-B-activity (PubMed : 24073260). Secreted form act as an important modulator during neuronal differentiation through interaction with STMN3 (By similarity). Plays a role in the clearance of immune complexes that arise during cell injury (By similarity).. Isoform 6. Does not affect caspase or BAX-mediated intrinsic apoptosis and TNF-induced NF-kappa-B-activity.. Isoform 4. Does not affect caspase or BAX-mediated intrinsic apoptosis and TNF-induced NF-kappa-B-activity (PubMed : 24073260). Promotes cell death through interaction with BCL2L1 that releases and activates BAX (PubMed : 21567405).
