Arabidopsis thaliana Research Reagents
Browse Arabidopsis thaliana (thale cress) antibodies and recombinant proteins — species-validated reagents for plant molecular biology, functional genomics, and systems biology. Arabidopsis is the premier dicot model organism and the first plant to have its genome fully sequenced (~135 Mb across 5 chromosomes, ~27,600 protein-coding genes). Its small size, rapid generation time (~6 weeks seed-to-seed), prolific seed production, self-fertilizing diploid genetics, efficient Agrobacterium-mediated floral-dip transformation, and comprehensive T-DNA insertion mutant collections (SALK, SAIL, GABI-Kat covering >95% of genes) have made Arabidopsis the foundation of modern plant biology. Our reagents support research across phytohormone perception and signal transduction (auxin/TIR1, gibberellin/GID1-DELLA, brassinosteroid/BRI1, ABA/PYR-PYL-RCAR, ethylene/ETR1, jasmonate/COI1), plant innate immunity (FLS2/BAK1-mediated PTI, NLR-mediated ETI, salicylic acid and jasmonic acid defense pathways), flowering time and circadian clock regulation (FLC, CO, FT, GI, CCA1, TOC1), epigenetics and chromatin biology (histone H3K4me3/H3K27me3/H3K9me2, DNA methylation via DRM2/CMT3/MET1, RdDM pathway), photomorphogenesis and light signaling (phytochromes, cryptochromes, phototropins, COP1/SPA), and root development and cell polarity (PIN auxin efflux carriers, PLT transcription factors). RUO
Species-Specific Validation Antibodies validated with confirmed reactivity to Arabidopsis targets using species-appropriate positive controls from seedling, rosette leaf, root, inflorescence, and silique tissue lysates.
Broad Target Coverage Phytohormone receptors and signaling components, defense-related proteins, transcription factors (WRKY, MYB, bHLH, AP2/ERF), histones and chromatin modifiers (H3K4me3, H3K27me3, H3K9ac), photosynthetic complexes (RuBisCO, LHCII, PSI/PSII), and metabolic enzymes.
Cross-Reactivity Data Detailed species cross-reactivity information provided on every product datasheet, enabling comparative studies across dicot (tomato, soybean, tobacco) and monocot (rice, maize, wheat) systems.
Multiple Applications Validated for WB, IHC (tissue sections and whole-mount), IF (protoplasts, root tips, pollen tubes), ELISA, and ChIP across plant molecular biology, functional genomics, and epigenetics research workflows.
Original Manufacturer In-house production under ISO 9001 & ISO 13485 quality systems — reliable supply, consistent lot-to-lot performance, and lot-specific CoA and validation data on every product page.
FAQs
How are your antibodies validated?
Every antibody is validated in its listed applications (WB, IHC, IF, ELISA) with supporting images and data on the product page. We use positive and negative controls plus knockout/knockdown verification where available.
Do you offer conjugated antibodies?
Yes — HRP, AP, biotin, FITC, PE, APC, Alexa Fluor, and other fluorochrome conjugates are available. Custom conjugation services are also offered for bulk orders.
Do your antibodies cross-react with crop species?
Many antibodies targeting conserved plant proteins (histones, RuBisCO, ubiquitin, photosystem subunits) show broad cross-reactivity across dicots and monocots. Target-specific cross-reactivity is listed on each product datasheet.
What is your replacement policy?
If a product does not perform as described under recommended conditions, contact us within 30 days for replacement or credit. Our technical team will help troubleshoot first.
Can I get custom antibodies?
Yes — our parent company AtaGenix offers full custom antibody development from immunogen design through hybridoma screening and scale-up production.
All products manufactured by AtaGenix Laboratories under ISO 9001 & ISO 13485 quality systems.
