Question (75779) | Human VEGF ELISA Kit (ab100663)

I would like to measure VEGF in urine using an ELISA. I saw that 100662 is recommended for urine samples, but can we still use 100663?? Also, could you please clarify the difference between 100662 and 100663??

Please note that ab100662 and ab100663 are similar kits that both measure levels of VEGF.

However ab100662 is best used for detecting VEGF in biological fluids such as cell culture supernatant, serum and plasma while ab100663 is best suited for use with cell and tissue extracts.
