Description:

Yashraj Biotechnology Ltd., established in 1999, is an ISO 13485:2016 and ISO 9001:2015 certified life sciences company specializing in the bulk manufacturing and supply of high-purity human native antigens, recombinant proteins, and diagnostic-grade monoclonal and polyclonal antibodies. Over more than two decades, YBL has expanded beyond IVD raw materials into Integrated Drug Discovery (IDD), offering human primary cells, induced pluripotent stem cells (iPSCs), and tailored bioprocess development services.

Salient Features

•  Ethical Biomedical Sourcing & Regulatory Compliance: Established approvals from the Government of India and statutory authorities for collecting biomedical fluids from an extensive nationwide network of hospitals, enabling sustainable native biomarker isolation and research.
•  Multi-Platform Expression Systems: Advanced research, development, and bulk manufacturing capabilities utilizing bacterial, yeast, insect cell (baculovirus), and mammalian expression systems (CHO, HEK293).
• Antibody Engineering & Characterization: Dedicated platforms for hybridoma, phage display, and goat/rabbit immunization, characterized via Surface Plasmon Resonance (SPR / Biacore) for high-affinity paired-assay performance.
•  Global Cold Chain Logistics: Over two decades of proven cold chain management delivering temperature-sensitive biomolecules to global IVD manufacturers, CROs, and research institutions worldwide.

Product Portfolio

•  Tumor & Oncology Markers: CA 15-3, CA 19-9, CA 125, CA 72-4, Total PSA, Free PSA, CEA, AFP, Beta-hCG, Thyroglobulin (TG), and Kappa/Lambda Free Light Chains.
•  Cardiac & Vascular Markers: Troponin-I, NT-proBNP, BNP, D-Dimer, Myoglobin, CK-MB, and PAPP-A.
•  Inflammation & Sepsis Markers: C-Reactive Protein (CRP / hsCRP), Procalcitonin (PCT), and Calprotectin.
• Renal Markers: Cystatin-C, Alpha-1-Microglobulin (A1M), Beta-2-Microglobulin (B2M), and NGAL (native, wild-type, and mutant).
• Infectious Disease Markers: HBsAg (subtypes Ad and Ay), HCV antigens, Recombinant Streptolysin-O (Stabilized SLO), and respiratory targets (including SARS-CoV-2 antigens).
• Autoimmune Markers: Proteinase-3 (PR3), Myeloperoxidase (MPO), and Calprotectin.
•  Human Native Antigens: Placental Ferritin, Soluble Transferrin Receptor (sTfR), hCG, and native disease-state human serum/plasma proteins.
•  Recombinant Antigens: Troponin-I, Procalcitonin (PCT), Calprotectin, Neuron-Specific Enolase (NSE), Stabilized SLO, and NGAL.
•  Monoclonal Antibodies: Matched pairs and single clones against AFP, CRP, PSA, Thyroglobulin (Anti-TG), Troponin-I, PCT, and Calprotectin (validated for ELISA, CLIA, lateral flow, and turbidimetric platforms).
• Polyclonal Antibodies: Host-specific polyclonal antibodies (goat and rabbit origin), including Goat Anti-CRP (fractionated/affinity purified), Goat Anti-Cystatin-C, Goat Anti-Ferritin, and anti-immunoglobulin fractions.
• Human Primary Cells & Stem Cell Models (IDD Solutions): Ethically derived human primary cells, Induced Pluripotent Stem Cells (iPSCs), 3D/in vitro disease models, and specialized cell expansion kits.

Specialized IVD & IDD Services

•  YBL-Vega Platform: Phage display and recombinant antibody generation for diagnostic and therapeutic research targets.
•  Bioprocess Development & Bulk Fermentation: Scale-up manufacturing, downstream AKTA chromatography purification, and lyophilization.
•  Contract Research & Assay Biology (CRO): Custom biomarker generation, cross-reactivity testing, assay validation, and lot-to-lot consistency assessments.
