Standards & Controls

Cosmo Bio USA offers a robust and expertly curated Standards & Controls portfolio, delivering essential reagents that ensure precision, reproducibility, and validation across molecular biology, proteomics, immunology, histology, and biomedical research. Cosmo Bio Co., Ltd. provides AGE-modified plasma and serum standards for aging and metabolic disorder studies, while CSR contributes highly purified DNA samples and 5FU-BSA conjugates for nucleic acid and drug interaction research. TYB supports accurate nucleic acid visualization with DNA ladders, dyes, and electrophoresis markers. MBL International enhances immunology and cell biology workflows with recombinant kinase controls and autophagy-related standards like Anti-LC3 lysates. Trans Genic Inc. (KAL) supplies critical immunoglobulin isotype controls—mouse IgG1, IgG2a, IgG2b, and IgM—to reduce background in flow cytometry and IHC.

Primary Cell Co., Ltd. (PMC) adds protein molecular weight markers for electrophoresis and Western blotting. BQC offers a full range of histology and cytology stains, including Masson’s Trichrome, PAS, Alcian Blue, and oxidative stress detection dyes like DHE and DHR 123. Atlas Antibodies provides PrEST antigens—defined recombinant protein fragments for antibody validation and proteomics standardization. DCB’s SIMASIMA series delivers precision prestained protein markers, while Beacle, Inc. (BEC) offers multicolor Western blot markers and Ponceau S staining for membrane visualization. YMS supports genomic studies with a Standard Mixture for GC Content Analysis using Nuclease P1. IST supplies fluorescent dyes and calibration reagents for molecular diagnostics and cell-based assays. EVEC Inc. (EVC) rounds out the offering with antigens and positive controls tailored for infectious disease and serological assay validation. Together, these validated tools position Cosmo Bio USA as a trusted partner in delivering reproducible, publication-ready results across the life sciences.
