Scientists are Checking out the potential to culture cells that produce LAL. This improvement could probably remove the need to catch the horseshoe crabs from the biomedical business.
On the other hand, You can find worry amongst pharmaceutical scientists (sixty six% of Those people interviewed) that the extra validation associated with using the substitution involves a considerable quantity of extra time and expenditure.
