Buffer Detection Kit for Magnetic Beads
1 Kit
Space Saver Option（チェックを入れると箱詰めから袋詰めに変更となりますのでご注意ください） Customers purchasing multiple kits may choose to save storage space by eliminating the kit packaging and receiving their multiplex assay components in plastic bags for more compact storage.
A kit suitable for quantitative array of a wide variety of proteases in biological samples, utilizing FTC-casein as a substrate. Enzyme activities that have been detected with this assay kit include: chymotrypsin, elastase, plasminogen, PRONASE® Protease, subtilisin, thermolysin, and trypsin.

A Fluorescent-Casein Substrate, Incubation Buffer, Assay Buffer Trypsin Standard, and a user protocol.
• FTC-casein should be stored at -20°C and is stable for one year from the date of purchase. FTC-casein stored at 4°C is stable for 2-3 days. Several freeze-thaw cycles will lead to a minor increase in the background fluorescence, so following initial thawing, we suggest that this reagent be divided into 5 aliquots. FTC-casein is light sensitive and should be protected from light. • Protease positive control should be stored at -20°C. As with many proteases, trypsin is susceptible to autolysis and you may notice a reduction in trypsin activity with time, even if stored at -20°C. • Incubation buffer and assay buffer may be stored at 4°C or -20°C.
