General Research Tool Antibodies: Anti-Tag, GFP & More

They serve as versatile tools across multiple fields of biomedical research.

This category includes the workhorse reagents that underpin a broad range of experiments across cell, molecular, and protein biology. The anti-tag antibodies allow sensitive, reproducible detection and purification of recombinant fusion proteins: the anti-His (N-terminal), anti-GFP, anti-EBFP, and anti-STREP-II tag antibodies are ideal for Western blotting, immunoprecipitation, and affinity-tag verification of expressed constructs. Furthermore, AVS Bio offers an alpha-1-antitrypsin (A1AT) panel. Alongside wild-type A1AT, AVS Bio supplies the engineered Pittsburgh and Portland variants. Our spotlight product in this category is the mass-spectrometry-grade Lys-N endoprotease, which specifically hydrolyzes the peptide bond at the N-terminal side (amino side) of lysine residues. It is a key enzymatic tool for proteomics, offering complementary cleavage specificity to trypsin for peptide sequencing and PTM analysis.

Featured products: Lys-N (lysyl endoproteinase), widely used for proteomics and mass spectrometry sample preparation.
