General description

Mouse monoclonal antibody generated by immunizing Balb/c mice with the specified immunogen and fusing splenocytes with myeloma cells. Recognizes K29-, K48-, and K63-linked polyubiquitinylated and monoubiquitinylated proteins.
Recognizes K29-, K48-, and K63-linked polyubiquitinylated and monoubiquitinylated proteins, but not free ubiquitin, in Raji cells.
This Anti-Ubiquitin Mouse mAb (FK2) is validated for use in ELISA, Immunoblotting, Immunoprecipitation, Immunofluorescence for the detection of Ubiquitin.

Immunogen

human
unpurified polyubiquitinylated lysozyme

Application


ELISA (see application references)
Immunoblotting (1:1000)
Immunoprecipitation (see application references and comments)
Immunofluorescence (see application references)

Packaging

Please refer to vial label for lot-specific concentration.

Warning

Toxicity: Standard Handling (A)

Physical form

In PBS.

Preparation Note

Raji cells

Reconstitution

Following initial thaw, aliquot and freeze (-20°C). Store diluted antibody at 4°C for up to 1 month.

Other Notes

Does not recognize free ubiquitin. For immunoprecipitation, once the antibody is immobilized, it demonstrates affinity for free ubiquitin as well as for poly- and monoubiquitinylated proteins. Antibody should be titrated for optimal results in individual systems.

Systemic oxygen restriction (SOR) is prevalent in numerous clinical conditions, including chronic obstructive pulmonary disease (COPD), and is associated with increased susceptibility to viral infections. However, the influence of SOR on T cell immunity remains uncharacterized. Here we show the

Large cytosolic protein aggregates are removed by two main cellular processes, autophagy and the ubiquitin-proteasome system, and defective clearance of these protein aggregates results in proteotoxicity and cell death. Recently, we found that the eIF2α kinase heme-regulated inhibitory (HRI) induced

Tumor-derived extracellular vesicles (TEV) "educate" healthy cells to promote metastases. We found that melanoma TEV downregulated type I interferon (IFN) receptor and expression of IFN-inducible cholesterol 25-hydroxylase (CH25H). CH25H produces 25-hydroxycholesterol, which inhibited TEV uptake. Low CH25H levels in leukocytes

Ubiquitin (Ub) and Ub-like proteins (Ubls) such as NEDD8 are best known for their function as covalent modifiers of other proteins but they are also themselves subject to post-translational modifications including phosphorylation. While functions of phosphorylated Ub (pUb) have been
