Routes are assessed according to your sequence, specifications and research application.
For research and development use. Project acceptance is subject to technical feasibility and agreed specifications.
What we do
A thoughtful approach to
peptide development.
From a custom sequence to an existing process that needs improvement, we assess the scientific requirements before defining the work.
Process development & optimisation
Route development and optimisation for reaction efficiency, impurity control and reproducibility, with scale-up and technology-transfer planning.
Difficult sequences & impurities
Development support for aggregation, incomplete coupling, oxidation and complex purification profiles, including peptide-related impurity investigation.
Purification & analytical support
Purification strategy and analytical characterisation, with suitable facilities or qualified partners where required. Testing is agreed for each project.
Project scope, timelines and commercial terms follow feasibility review.
Discuss your requirementOur synthesis approaches
Different sequences.
Different routes forward.
Sequence complexity, purity, quantity and stability guide the choice of synthesis strategy.
01 / Solid-phaseSPPS
Solid-phase
peptide synthesis
Sequential amino-acid assembly on a polymeric support, with evaluation of resin, coupling, deprotection, cleavage and purification.
Assembly on a solid support
02 / Solution-phaseLPPS
Solution-phase
peptide synthesis
Synthesis in solution, allowing evaluation of homogeneous reactions, reaction monitoring and intermediate isolation for selected peptides and fragments.
Reaction and isolation in solution
03 / HybridCombined
Hybrid
peptide synthesis
A combination of solid-phase and solution-phase methods, including separate fragment preparation followed by coupling or further processing where appropriate.
Complementary methods, combined
About Zenithra
Built on science.
Focused on your
requirement.
Zenithra Sciences Private Limited
Gandhinagar, Gujarat, India
We are a peptide research and development startup with a method-flexible approach to customised synthesis and process development.
Our work is supported by doctoral-level expertise in liquid-phase peptide synthesis and practical experience across solid-phase and solution-phase peptide development.
Sequence-specific assessment
Development considers molecular complexity, aggregation tendency, target purity, quantity and intended application.
Responsible development
We aim to improve reaction efficiency while reducing avoidable reagent and solvent use.
Quality & analytical approach
Clear specifications.
Documented development.
Quality begins with defined project requirements. Depending on the agreed scope, documentation may include synthesis and purification records, HPLC chromatograms, mass-analysis results, a certificate of analysis and project-specific reports.
An agreed analytical plan
Where instruments are not available internally, qualified external laboratories or institutional facilities may support analysis. The testing plan and location will be communicated to you.
RESEARCH & DEVELOPMENT USE
Research-grade peptides are not intended for direct human or veterinary administration, diagnosis or therapeutic use. Clinical, therapeutic or regulated supply requires appropriately licensed and compliant facilities.
