This update turns Gene Search into a complete qPCR assay design tool: • qRT-PCR primer design — generate optimized primer pairs for any mRNA directly on your device, with expected product size, Tm, and GC content for each pair • Exon-junction detection — pairs that span exon–exon junctions are flagged and prioritized, so your assays are cDNA-specific • One-tap verification — open any designed pair in NCBI Primer-BLAST with everything prefilled • CSV export — share complete primer, siRNA, and sgRNA result sets ready for oligo ordering • Rat support — search rat genes alongside human and mouse • Faster everywhere — smart caching makes revisiting genes nearly instant

Gene Search 5.0.0 • New: Tissue Expression tab — view median gene expression across human tissues (GTEx), shown as a ranked bar chart on any gene page. • Security — NCBI API credentials moved out of the source code into local environment config; key rotated. • Reliability — all data services now share one NCBI configuration, with the API key applied consistently for better rate limits.

What's New in Version 4.0.1 • New: RNA Tool Designer — generate siRNA and sgRNA candidates directly in the app • New: Disease Associations — identify potential diseases linked to any gene via OMIM • Improved: Cleaner, more modern interface throughout • Fixed: Mouse gene results incorrectly showing "Human" label

What's New in Version 2.1.1 This update brings a fresh new look and powerful new research tools. New Features 1. RNA Tool Designer — generate siRNA and sgRNA candidates directly in the app. Select any mRNA accession, and the app fetches the sequence from NCBI and applies standard design rules to rank the best candidates for gene silencing and CRISPR editing. 2. Design Improvements 3. Cleaner, more modern interface with improved typography and spacing 4. Gene cards now display with a streamlined layout and organism badges 5. Pill-style search bar and species toggle for a more intuitive feel 6. Recent searches now appear as horizontal scrollable chips 7. Tab navigation on gene detail pages is now horizontally scrollable

I've reorganized the gene detail page into a tabbed layout! Now instead of showing all information at once, the page has: 4 tabs at the top: Description - Gene description, summary, function, location, aliases, related genes, and database statistics Publications - Related publications from PubMed mRNA - RNA sequences with sharing and primer design functionality Protein - Associated protein information

1. RNA Sequence Reference Numbers (RefSeq). Displays RNA sequences in the gene detail page with: - RefSeq accession numbers (NM_, NR_, XM_, XR_) - Sequence type badges (mRNA, ncRNA, Predicted RNA) - Sequence length in base pairs 2. Primer Design with BLAST. Users can design primers with NCBI Primer-BLAST tool.

In this updated version, users can explore protein sequences and structures in addition to gene descriptions. Users also can share gene and protein information with colleagues.
