Overview
This is a polyclonal anti-KRT81 antibody raised in Rabbit, conjugated with HRP, with confirmed utility in ELISA. Designed to detect KRT81 in Human, supporting researchers in signal transduction contexts.
Key elements and design rationale
- Immunogen: Recombinant Human Keratin, type II cuticular Hb1 protein (3-505AA) — determines the epitope region recognized; confirm epitope compatibility with your sample preparation and expected PTMs.
- Host (Rabbit): Requires anti-rabbit-IgG secondary reagents. Mismatched secondaries result in no signal. Consider host species when multiplexing.
- Polyclonal: Recognizes multiple epitopes — robust signal across varied preparations, with inherent lot-to-lot variability. Isotype controls and lot qualification recommended.
- Isotype (IgG): Secondary antibodies and isotype controls must match IgG from Rabbit. Relevant for multiplexing and Protein A/G compatibility.
- Purification (Protein G purification): Reduces non-specific immunoglobulin populations, improving signal-to-noise in quantitative immunoassay formats.
- HRP conjugate: Direct chromogenic (TMB/OPD) or chemiluminescent (ECL) detection. Quench endogenous peroxidase in tissue applications. No secondary required.
Biological background
KRT81 (also known as 1, basic, ghHb 1, ghHb1, ghHkb 1, ghHKb1, hair, Hair keratin K2.9, Hard keratin type II 1, HB 1, HB1, hHAKB2 1, K2.9, K81, Keratin 81, Keratin, Keratin hair basic 1, Keratin type II cuticular Hb1, Keratin-81, Keratin81, KRT 81, KRT81, KRT81_HUMAN, KRTHB 1, KRTHB1, Metastatic lymph node 137 gene protein, MLN 137, MLN137, type II cuticular Hb1, Type II hair keratin Hb1, Type-II keratin Kb21) is a protein studied in Human systems. Expression levels, subcellular localization, and post-translational modifications vary across cell types, tissues, and disease states — factors that influence antibody-based detection outcomes. Researchers are encouraged to consult UniProt, NCBI Gene, and primary literature for current annotation of KRT81 biology relevant to signal transduction.
Common research applications
- ELISA: Sandwich or indirect ELISA quantifies soluble/secreted target in biological fluids or cell culture supernatants.
Notes for experimental interpretation
- Isotype controls: Include IgG from Rabbit at equivalent concentration to assess non-specific background.
- Cross-reactivity/isoforms: Polyclonal preparations may cross-react with related proteins or isoforms — validate with siRNA KD, KO lysate, or recombinant protein controls.
- Matrix effects: Sample matrix (serum, plasma, lysate, homogenate) may influence performance; pilot dilution linearity and spike-recovery experiments before full quantitative studies.
- Species reactivity: Confirmed for Human; extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
KRT81 is a protein target in Human biology. This polyclonal antibody raised in Rabbit detects KRT81 and is validated for ELISA applications.
This antibody is reported reactive against Human. Immunogen derived from Human. Cross-reactivity with unlisted species should not be assumed — contact us or consult the datasheet for homology data.
Supplier reports performance in ELISA. Dilution optimization, blocking, and appropriate controls are required per format. Contact BioHippo for recommended working concentrations.
HRP enables direct chromogenic (TMB/OPD) or chemiluminescent (ECL) detection — no secondary needed. Block endogenous peroxidase in tissue applications before applying this antibody.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — lysate/cell line expressing KRT81; (3) Negative control — siRNA KD or KO sample to confirm specificity; (4) Dilution linearity — verify proportional signal decrease for quantitative applications.
