USP18 Antibody, Biotin conjugated

Overview

This polyclonal anti-USP18 antibody raised in Rabbit, conjugated with Biotin, tested in ELISA. Designed to detect USP18 in Human for cell biology research.

Key elements and design rationale

• Immunogen: Recombinant Human Ubl carboxyl-terminal hydrolase 18 protein (18-118AA) — determines epitope; confirm sample prep compatibility.
• Host (Rabbit): Requires anti-rabbit-IgG secondary matching isotype IgG.
• Polyclonal: Multiple epitopes = robust signal; lot-to-lot variability — include controls.
• Isotype (IgG): Match secondary, Protein A/G, and isotype controls to IgG.
• Purification (Protein G purification): Enriches Ig classes; reduces non-specific background.
• Biotin: Streptavidin/avidin amplification; block endogenous biotin in biotin-rich samples.

Biological background

USP18 (also: 43 kDa ISG15 specific protease, 43 kDa ISG15-specific protease, EC 3.1.2., hUBP43, Interferon Stimulated Gene 43 kD, ISG15 Specific Processing Protease, ISG15-specific-processing protease, ISG43, Ubiquitin Specific Peptidase 18, Ubiquitin Specific Protease 18 43 kD, Ubiquitin Specific Protease 18, Ubl carboxyl terminal hydrolase 18, Ubl carboxyl-terminal hydrolase 18, Ubl thioesterase 18, Ubl thiolesterase 18, Ubp15, UBP18_HUMAN, USP18) — studied in Human systems. Expression, localization, and PTMs vary across cell types and disease states. Consult UniProt, NCBI Gene, and primary literature for current USP18 annotation relevant to cell biology.

Common research applications

• ELISA: Quantify soluble target; ensure samples within the linear detection range.

Notes for experimental interpretation

• Isotype controls: IgG from Rabbit at equivalent concentration.
• Cross-reactivity: Polyclonal: validate with KO/KD controls.
• Matrix effects: Verify dilution linearity in your sample matrix.
• Reactivity: Confirmed for Human; extrapolation requires validation.

This product is a polyclonal antibody purified from rabbit antiserum.
