Frequently Asked Questions
What are research-grade biosimilars?
Research-grade biosimilars are laboratory-produced proteins designed to mimic the structure and function of approved biologic drugs. They are used in preclinical studies, assay development and other non-clinical applications.
How do research-grade biosimilars differ from therapeutic biosimilars?
Research-grade biosimilars are intended for laboratory and research purposes only. They are not subject to the same regulatory scrutiny as therapeutic biosimilars, which must undergo clinical trials and approval processes for patient use.
Are research-grade biosimilars the same as reference biologics?
No. Research-grade biosimilars are designed to be similar in structure and function to reference biologics but are not identical. They are primarily used for assay development, drug screening and in vitro/in vivo research.
Are research-grade biosimilars produced using the same expression systems as the original biologics?
They may be produced in similar systems (e.g., CHO cells, E. coli, yeast), but there can be differences in post-translational modifications, glycosylation patterns or impurities.
How is the quality of research-grade biosimilars ensured?
Quality is assessed through purity analysis (SDS-PAGE, HPLC, mass spectrometry), bioactivity assays and binding affinity tests (e.g., ELISA, SPR, BLI).
What are common applications of research-grade biosimilars?
Preclinical drug screening; assay development and validation (ELISA, Western blot, flow cytometry); mechanism of action studies; and comparative studies against reference biologics.
Which conjugates are available and which should I choose?
Conjugated biosimilars are available with Biotin, FITC, APC, PE, DyLight®488 or HRP. Biotin suits flexible detection with streptavidin-based systems; FITC/APC/PE/DyLight®488 are direct fluorophores for flow cytometry and IF; HRP is ideal for colorimetric ELISA and Western blot detection.
