hand up if you ’re lactose intolerant . Quite a few of you , huh ? Well , welcome to the grand world of scientific discipline , where researchers havegenetically orchestrate a moo-cow , just for you .
A squad from AgReasearch and the University of Waikato in New Zealand have genetically mastermind a cow to make milk that ’s hypoallergenic and supererogatory eminent in other protein . The calf — called Daisy — bring about milk with majorly depleted horizontal surface of the milk protein β - lactoglobulin ( BLG ) , and increase levels of all casein Milk River protein .
The research worker got to this degree by first using mice designed to “ mime the mammary secretor of a sheep ” ( no , I had no idea that was a thing either ) and then create an RNA hinderance to block the production of the particular protein . The calf was then mastermind to express the same two micro RNAs , and so produced milk without the allergen .
However , this is a long , long means from being the milk sugar - spare moo-cow ’s Milk River that I cognise some people are dying for . It ’s passing expensive , has n’t been tested for human consumption , andas one doctor pointed out , it only stop one of the allergen proteins that citizenry can react to — and actually hike up another . There ’s also the curious and unknown crusade of the calf being born without a shadower . Still , give it a decade or two , and allergic reaction - costless milk might yet make it to the refrigerator shelf of your local memory .
