Product Description

The MHC Class I Antigen Processing and Presentation Antibody Sampler Kit provides an economical means to examine key proteins associated with the processing and presentation of MHC class I-restricted antigens. The provided antibodies allow monitoring of total protein levels. The kit includes enough antibodies to perform two western blot experiments with each primary antibody.

Specificity / Sensitivity

Each antibody in the MHC Class I Antigen Processing and Presentation Antibody Sampler Kit detects endogenous levels of its target protein. Calreticulin (D3E6) XP® Rabbit mAb recognizes endogenous levels of total calreticulin protein. Ubiquitin (E4I2J) Rabbit mAb recognizes endogenous levels of free ubiquitin and polyubiquitinated proteins. This antibody is able to detect free ubiquitin, linear polyubiquitin (M1-linked), and homotypic polyubiquitin chains consisting of K6, K11, K27, K29, K33, K48 and K63 linkages. HLA-G (E8N9C) XP® Rabbit mAb recognizes endogenous levels of total HLA-G protein. Calnexin (C5C9) Rabbit mAb detects endogenous levels of total calnexin protein. TAP2 (E8G5I) Rabbit mAb recognizes endogenous levels of total TAP2 protein. This antibody does not cross-react with TAP1 protein. PSMB8/LMP7 (D1K7X) Rabbit mAb recognizes endogenous levels of total PSMB8/LMP7 protein. This antibody recognizes both 28 kDa precursor and 23 kDa mature forms of PSMB8/LMP7 and does not cross-react with PSMB5 protein. This antibody recognizes proteins of unknown origin in the 80-100 kDa range. TAP1 (E4T4F) Rabbit mAb recognizes endogenous levels of total TAP1 protein. This antibody does not cross-react with TAP2 protein. β2-microglobulin (D8P1H) Rabbit mAb recognizes endogenous levels of total β2-microglobulin protein. IFNGR1 (E444) Antibody recognizes endogenous levels of total IFNGR1 protein.

Source / Purification

Monoclonal antibodies are produced by immunizing animals either with a recombinant protein specific to the carboxy terminus of human TAP1 protein or a synthetic peptide corresponding to residues near the amino terminus of human calreticulin protein, the carboxy terminus of human PSMB8/LMP7 protein, Gly35 of human ubiquitin protein, Leu102 of human HLA-G protein, Val57 of human β2-microglobulin protein, Val485 of human TAP2 protein, or Pro52 of human calnexin protein. Polyclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu444 of human IFNGR1 protein. Polyclonal antibody is purified by protein A and peptide affinity chromatography.

Background

The predominant function of class I MHC/β2-microglobulin dimers, which are expressed on the surface of most nucleated cell types, is to modulate the adaptive immune response by presenting proteolytic peptide fragments from cytosolic proteins to cytotoxic CD8+ T cells. In order for self and nonself peptides to be presented by MHC class I molecules, the peptide fragments must first be derived from polyubiquitinated proteins that undergo degradation via the ubiquitin-proteasome system. In the context of inflammatory processes, the enzymatic core of the proteasome can be shaped by IFNγ signaling to contain subunits, such as PSMB8/LMP7, which enhance the presentation of antigenic peptides by antigen presenting cells (1). The resulting cytosolic peptide fragments generated through ubiquitin-dependent proteasomal degradation are then transported into the ER lumen via the peptide transporters, TAP1 and TAP2, where the activity of multiple chaperone proteins, such as calnexin and calreticulin, facilitate loading onto class I MHC/β2-microglobulin dimers for transport to the Golgi and eventually, the cell surface (2-6). Defects in the expression of multiple components of the class I antigen presenting machinery have been observed in both solid and liquid tumors, which serves as a mechanism of tumor-immune evasion (7).
