Calcifediol 31-39 calreticulin Rattus norvegicus 180-186 821943-13 1976 The Cal-BP content of human serum is approximately 10(-5) M, whereas the calcifidiol content is approximately 10(-7) M. Normally, the dominant moiety of human plasma Cal-BP is the apoprotein. Calcifediol 73-84 calreticulin Rattus norvegicus 166-172
