Target Name: 
Human GA733-1 Protein, Human GA7331 Protein, Human GP50 Protein, Human M1S1 Protein
Source:
The extracellular domain of Human TROP-2 protein (NP_002344.2) (Met1-Thr274) with C-terminus His tag is expressed in CHO cells.
Molecular Weight:
The 259 amino acid protein has a predicted molecular weight of 29.4 kDa. The protein migrates at approximately 35-45 kDa on SDS-PAGE in DTT-reduced and non-reduced conditions.
Purity:
>95% based on SDS-PAGE under reducing condition
Formulation:
1xPBS buffer, pH7.4, 0.22 µm filtered
Endotoxin Level:
Not Tested
Vial Size:
25µg, 100µg
Protein Concentration:
25µg size is bottled at 0.2mg/mL concentration. 100 µg size is bottled at lot-specific concentration.
Storage and Handling:
Quick spin the vial after receiving. Unopened vial can be stored at 4°C for 2 weeks or at -20°C and below for six months. The protein can be further diluted to 0.1 mg/mL with 0.22 µm filtered PBS buffer.  This stock solution should be aliquoted and stored at ≤ -70°C to minimize the freeze/thaw cycles. Carrier proteins such as FBS and BSA need to be added if further dilution is needed.
