Overview
This is a polyclonal anti-mpt63 antibody raised in Rabbit, conjugated with HRP, with confirmed utility in ELISA. It is designed to detect mpt63 protein in Mycobacterium tuberculosis and supports researchers working in others contexts where consistent antibody performance is required.
Key elements and design rationale
- Immunogen: Recombinant Mycobacterium tuberculosis Immunogenic protein MPT63 protein (30-159AA) — the immunizing antigen determines the epitope region; confirm epitope compatibility with sample preparation and expected post-translational modifications.
- Host species (Rabbit): Requires anti-rabbit-IgG secondary reagents. Use matched secondaries to avoid no-signal or cross-reactivity issues.
- Polyclonal format: Recognizes multiple epitopes, providing robust signal across varied preparations and species variants. Inherent lot-to-lot variability requires appropriate controls.
- Isotype (IgG): Compatible with standard Protein A/G purification and widely supported by secondary reagents. Include an isotype-matched control at equivalent concentration.
- Purification (Protein G purification): Enriches for specific immunoglobulin classes, reducing non-specific populations and improving signal-to-noise.
- HRP conjugate: Enables direct chromogenic (TMB/OPD) or chemiluminescent (ECL) detection. Quench endogenous peroxidase before use in tissue assays.
Biological background
mpt63 (also referred to as mpt63, Rv1926c, MTCY09F9.38, Immunogenic protein MPT63, 16 kDa immunoprotective extracellular protein, Antigen MPT63) is a protein target studied in Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv) systems. Expression levels, subcellular localization, and post-translational modifications vary across cell types, tissues, and disease states — factors that influence antibody-based detection and experimental design. Consult UniProt, NCBI Gene, and primary literature for current annotation of mpt63 biology, including known isoforms, interactors, and disease-relevant expression patterns in others.
Common research applications
- ELISA: Sandwich or indirect ELISA can quantify soluble target in biological fluids or culture supernatants. Ensure samples fall within the linear detection range.
Notes for experimental interpretation
- Isotype controls: Use an isotype-matched (IgG from Rabbit) control at equivalent concentration to assess non-specific background.
- Cross-reactivity: Polyclonal preparations may cross-react with related proteins or isoforms. Orthogonal validation (siRNA, KO lysate, recombinant protein) is recommended to confirm signal specificity.
- Matrix effects: Sample matrix (serum, plasma, lysate, homogenate) can affect performance. Pilot dilution linearity and spike-recovery experiments are recommended for quantitative studies.
- Species reactivity: Confirmed for Mycobacterium tuberculosis. Extrapolation to untested species requires empirical validation given potential epitope sequence divergence.
This product is a polyclonal antibody purified from rabbit antiserum.
mpt63 is a protein target in Mycobacterium tuberculosis biology. This polyclonal antibody raised in Rabbit is designed to detect mpt63 in ELISA applications, with IgG isotype.
This antibody is reported reactive against Mycobacterium tuberculosis. The immunogen was derived from Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv). Cross-reactivity with other species should not be assumed without documented data or empirical testing.
The supplier reports performance in ELISA. Each application requires independent dilution optimization, blocking conditions, and appropriate controls. Performance in unlisted applications requires empirical testing.
HRP conjugation enables direct detection using TMB (colorimetric) or ECL (chemiluminescent) substrates without a secondary antibody. Quench endogenous peroxidase in tissue assays before applying this antibody.
Recommended: (1) Isotype control — IgG from Rabbit at matching concentration for non-specific background; (2) Positive control — known mpt63-expressing cell/tissue; (3) Negative control — knockdown or knockout sample to confirm signal specificity; (4) Dilution linearity — verify proportional signal decrease to confirm quantitative linearity in your matrix.
