Overview
This is a polyclonal anti-PRA1 antibody raised in Rabbit, conjugated with Biotin, with confirmed utility in ELISA. It is designed to detect PRA1 protein in Candida albicans and supports researchers working in others contexts.
Key elements and design rationale
- Immunogen: Recombinant Candida albicans pH-regulated antigen PRA1 protein (16-299AA) — determines the epitope region; confirm compatibility with sample preparation and expected post-translational modifications.
- Host species (Rabbit): Requires anti-rabbit-IgG secondary reagents for indirect detection.
- Polyclonal format: Recognizes multiple epitopes for robust signal; inherent lot-to-lot variability requires appropriate controls.
- Isotype (IgG): Matched secondary antibodies and isotype controls required. Compatible with standard Protein A/G purification workflows.
- Purification (Protein G purification): Enriches for specific immunoglobulin classes; reduces non-specific background vs. crude antisera.
- Biotin conjugate: Amplified detection via streptavidin/avidin reporters. Block endogenous biotin in biotin-rich tissue samples.
Biological background
PRA1 (also referred to as PRA1, FBP1, CAALFM_C406980WA, CaO19.10623, CaO19.3111, pH-regulated antigen PRA1, 58 kDa fibrinogen-binding mannoprotein) is a protein target studied in Candida albicans systems. Expression, subcellular localization, and post-translational modifications vary across cell types and disease states — factors critical to antibody-based detection design. Consult UniProt, NCBI Gene, and primary literature for current annotation of PRA1 biology in others.
Common research applications
- ELISA: Quantification of soluble target in biological fluids or culture supernatants. Ensure samples are 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. Orthogonal validation (siRNA, KO lysate) is recommended.
- Matrix effects: Sample matrix can affect performance; pilot dilution linearity and spike-recovery experiments are advised for quantitative studies.
- Species reactivity: Confirmed for Candida albicans. Extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
PRA1 is a protein target in Candida albicans biology. This polyclonal antibody raised in Rabbit is designed to detect PRA1 in ELISA applications, with IgG isotype.
Reported reactive against Candida albicans. Immunogen derived from Candida albicans. Cross-reactivity with other species should not be assumed without documented data or empirical testing.
Reported for ELISA. Each format requires independent dilution optimization and appropriate controls. Unlisted applications require empirical testing.
Biotin enables streptavidin/avidin-amplified detection. Block endogenous biotin in biotin-rich tissues.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — known PRA1-expressing cell/tissue; (3) Negative control — knockdown/knockout sample for specificity; (4) Dilution linearity — verify proportional signal decrease in your matrix.
