Some of the putative regions encode transporter proteins such as OCTN1 and OCTN2. Genetic analyses have tested the existence of three of these putative subspecies. Software tools have been developed in order to automatically identify putative genes. This putative protein was known as phosphatonin. Follicular DCs develop from putative mesenchymal precursors. And ORF 9 and 14 are identified as putative hydroxylation enzymes. Agmatine has been discussed as a putative neurotransmitter. However, many taxonomists found these putative species difficult to distinguish. Both tests failed to confirm the existence of the putative code. Groups that claimed actual or putative foreign ancestry were referred to as Ashrafs. Possible allusions are described as mere echoes of their putative sources. It is, however, difficult to explain the origin of a putative regolith. Severe angioedema cases may require desensitization to the putative allergen, as mortality can occur. The union resulting is called a putative marriage. Thousands of devices claiming to heal via putative or veritable energy are used worldwide.
