Allergen science · Kolkata, India
Advancing allergen science from source to protein.
Source Protein Technologies is building specialized capabilities for the sourcing, extraction, purification, characterization and recombinant production of allergenic proteins in India.
Dedicated to allergen science
Allergens are biological materials long before they are proteins.
An allergen preparation carries the history of its source. Pollen is defined by taxon and flowering window. House dust mites — Dermatophagoides spp. — depend on culture medium, temperature and humidity. Fungal material reflects strain and growth stage. Food allergens vary with cultivar, maturity and processing.
Source Protein Technologies is organised around that reality: a company dedicated to allergenic proteins and allergen source materials, building the sourcing, biological handling, processing, purification and analytical capabilities that this field asks for — in one place, in India.
Source integrity
Defined at origin
Identity, season and provenance recorded where the material is collected or cultured.
Biological handling
Living systems
Mites and fungi are grown, not bought. Conditions are set, held and documented.
Traceability
Source to vial
Each preparation stays linked to the material and the process that produced it.
The workflow
From source to characterized allergen.
Six stages, each one a discipline of its own. Select a stage to read what happens there.
Capabilities
Eight capabilities, one field.
Source collection and culturing through to protein chemistry, immunological analysis and recombinant expression — developed as a single connected capability rather than isolated services.
The science
Four disciplines meeting on one molecule.
Allergen research does not sit inside a single field. A single well-defined allergen requires the biology of its source, the chemistry of the protein, the immunology of the response it provokes, and the molecular tools to reproduce it.
01 · Environment
Where allergens come from
Aerobiology, taxonomy, seasonality and the ecology of allergen-bearing organisms.
02 · Biochemistry
What the protein is
Extraction chemistry, separation, structural integrity and quantification.
03 · Immunology
How it is recognised
IgE reactivity, epitope behaviour and the analytical methods that measure it.
04 · Molecular
How it is reproduced
Sequence-defined expression of allergens as consistent, characterized proteins.
Kolkata, West Bengal
Built in eastern India, for work that travels.
Source Protein Technologies is based in Kolkata. The region's climate, vegetation and long aerobiological record make it a substantive place from which to study allergen sources — and a practical base for building the infrastructure this work needs.
Our scientific intent is not local. We are building capabilities meant to hold up in national and international research, diagnostic and biotechnology collaborations.

RegionEastern India
Built for collaboration
Specialized work is rarely done alone.
Allergen science connects clinical practice, diagnostics, protein chemistry and molecular biology. We are set up to work alongside the people already doing that work.
Allergists & clinicians
Defined source materials and characterized allergens for clinical and translational research.
Diagnostic developers
Allergen inputs for assay development, evaluation and reference work.
Research groups
Collaboration on allergen sourcing, extraction, characterization and recombinant expression.
Biotechnology companies
Protein production and purification collaborations within the allergen field.
Pharmaceutical organizations
Scientific partnership on allergen preparation and analytical characterization.
Academic institutions
Joint projects, method development and student research in allergen biology.
About
A company organised around one field.
Source Protein Technologies is a biotechnology company in Kolkata, West Bengal, dedicated to allergenic proteins and the biological materials they come from.
Why we exist
Allergen work is usually split across places that do not talk to each other: material is collected in one setting, extracted in another, characterized somewhere else. Consistency is lost between the steps.
We are building the opposite arrangement — sourcing, culturing, extraction, purification, characterization and recombinant production developed together, by one group, with the same standards applied end to end. Our focus is deliberately narrow so the depth can be real.
The company is in an early, deliberate build phase. We describe what we are developing rather than what we might claim, and we would rather be judged on scientific rigour than on positioning.
Focus
Allergens only
One field, studied properly, instead of a broad catalogue of unrelated services.
Method
Documented practice
Conditions, provenance and analysis recorded so results can be repeated.
Posture
Open to collaboration
Built to work with clinicians, researchers and companies rather than around them.
Where we are
Kolkata, West Bengal, India.
Eastern India offers a rich and varied set of allergen sources, from regional pollen flora to the humid conditions that shape mite and fungal biology. We are building here, and collaborating well beyond here.
Capabilities
Sourcing, processing, protein science.
Eight capabilities being developed as one connected workflow, from the collection of biological source material to the expression of sequence-defined allergens.
Science & technology
Where environmental biology meets protein science.
Allergen research sits at the intersection of four disciplines. Our technical approach is built to hold all four at once.
Disciplines
01 · Environment
Environmental biology
Taxonomy, seasonality, aerobiology and the ecology of pollen, mites and fungi.
02 · Biochemistry
Protein biochemistry
Extraction chemistry, chromatographic separation, integrity and quantification.
03 · Immunology
Immunology
IgE reactivity and the immunological methods used to characterize allergens.
04 · Molecular
Molecular biotechnology
Sequence-defined expression, purification and analysis of recombinant allergens.
Approach
Reproducibility is the technical problem.
Natural allergen sources vary. Two collections of the same species can differ by season, site and handling; two mite cultures can differ by humidity alone. Most difficulties in allergen work trace back to that variability.
Our technical priorities follow from it: define the source, control the biology, standardise the chemistry, measure what you made, and move to recombinant proteins where a defined sequence is the better answer.
Define
Known material
Species, origin, season and handling recorded before anything is extracted.
Control
Set conditions
Media, temperature and humidity held and logged across culture cycles.
Measure
Analytical proof
Protein and immunological analysis on every preparation, not on assumption.
Collaboration
Work with us on allergen material and allergen proteins.
We are looking for scientific partners — clinical, academic and industrial — whose work needs well-defined allergen sources or characterized allergenic proteins.
Who we work with
If your work touches allergen material at any point, there is likely a useful conversation to have.
Research & academic
Groups working on allergen biology, protein chemistry or immunology, including joint projects, method development and student research.
Biotechnology & pharmaceutical
Organizations working with allergenic proteins who need sourcing, extraction, purification, characterization or recombinant expression support.
