The concentration of Vitronectin (VTN-N) (Cat. No. A400457 and A400458) is the same as CTS Vitronectin (VTN-N) (Cat. No. CTS279S3). However, the concentration of Vitronectin (VTN-N) (Cat. No. A14700 and A34801) is different from that of CTS Vitronectin (VTN-N). Why are the all the concentrations not the same?
The proteins are all the same. However, a different method is used to measure the protein concentration of Vitronectin (VTN-N) (Cat. No. A14700 and A34801) than the method used to measure protein concentration of Vitronectin (VTN-N) (Cat. No. A400457 and A400458) and CTS Vitronectin (Cat. No. CTS279S3). The same method is used to measure the protein concentrations of Vitronectin (VTN-N) (Cat. No. A400457 and A400458) and CTS Vitronectin (CTS 279S3).
