Meet Kavita—and Her Quest for “Good” Milk
Kavita is a busy mom in Pune who starts every morning with a glass of warm milk for her two children. When her younger son often complained of tummy aches afterward, she wondered whether “A2 milk”—a term she kept seeing on shop labels—could really make a difference. But how could she be sure the claims on each bottle were true?
Her search led her to A1/A2 genotyping, a simple DNA test that reveals which beta-casein protein a cow produces. And that test, in turn, brought her to GeneOmbio Technologies—the first NABL- and ISO/IEC 17025-accredited lab in the region to offer gold-standard Sanger sequencing for the CSN2 gene.
Why the “A” Matters: A1 vs A2 Beta-Casein
- Beta-casein is one of the major proteins in cow’s milk.
- A single DNA “letter” change in the CSN2 gene swaps the amino acid at position 67: histidine in A1 milk, proline in A2 milk.
- Some studies suggest A1 milk releases a peptide (BCM-7) during digestion that may cause discomfort for sensitive people, while A2 milk appears gentler on many stomachs.
For consumers like Kavita, the difference can mean fewer digestive upsets—and greater confidence in every sip.
How Genotyping Protects Everyone in the Dairy Chain
| For Families | For Dairy Farmers | For Brands & Retailers |
| Verify “A2” labels before buying | Select & breed A2-only animals | Differentiate products in a crowded market |
| Reduce trial-and-error diet changes | Command a premium price for certified A2 milk | Build trust with lab-verified claims |
| Support children and elders with sensitive digestion | Plan herd genetics with long-term clarity | Avoid regulatory penalties for mislabeling |
The Science Behind the testing
- Sample Collection– Raw milk, or tiny bit of hair, blood, or ear-punch from each cow is enough.
- PCR Amplification– We copy only the part of the CSN2 gene that matters.
- Sanger Sequencing– The gold-standard technique that reads every DNA letter with near-perfect accuracy.
- Clear Results– Each animal is labelled A1A1, A1A2, or A2A2—no guesswork.
Because Sanger sequencing can detect even a single DNA change, farmers and consumers alike can trust the outcome.
Kavita’s Outcome—and Yours
Armed with her new knowledge, Kavita asked her local milk supplier for a geneOmbio certificate. The report showed the herd was A2A2. Word spread in her apartment complex, and soon the same supplier saw demand rise—proof that transparent testing rewards honest producers.
