Overview
This is a polyclonal anti-S100A2 antibody raised in Rabbit, conjugated with FITC. Designed to detect S100A2 in Human, supporting researchers in signal transduction contexts.
Key elements and design rationale
- Immunogen: Recombinant Human Protein S100-A2 protein (1-98AA) — 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 (Antigen affinity purification): Reduces non-specific immunoglobulin populations, improving signal-to-noise in quantitative immunoassay formats.
- FITC conjugate: Direct fluorescence (Ex ~490 nm / Em ~525 nm). Susceptible to photobleaching — use antifade reagents; protect from light.
Biological background
S100A2 (also known as CAN19, MGC111539, Protein S 100L, Protein S-100L, Protein S100 A2, Protein S100-A2, Protein S100L, S100 A2, S100 calcium binding protein A2, S100 calcium-binding protein A2, S100A2, S100L, S10A2_HUMAN) 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 S100A2 biology relevant to signal transduction.
Common research applications
- Refer to the product datasheet for confirmed application data.
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.
S100A2 is a protein target in Human biology. This polyclonal antibody raised in Rabbit detects S100A2 and is validated for immunoassay 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.
Application data not specified — review the product datasheet or contact our technical team.
FITC (Ex ~490 nm / Em ~525 nm) enables direct fluorescence without secondary. Protect from light; use antifade mounting for slides. FITC is susceptible to photobleaching.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — lysate/cell line expressing S100A2; (3) Negative control — siRNA KD or KO sample to confirm specificity; (4) Dilution linearity — verify proportional signal decrease for quantitative applications.
