Molecular Weight:

The 525 amino acid protein has a predicted molecular weight of 58.4kDa. The protein migrates at approximately 70-80kDa on SDS-PAGE with DTT-reduced conditions.

Purity:

>95% based on SDS-PAGE under reducing condition

Formulation:

1xPBS buffer, pH7.4, 0.22 µm filtered

Vial Size:

25µg, 100µg

Endotoxin Level:

Not Tested

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. An unopened vial can be stored at 2-8°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 BSA needs to be added if further dilution is needed.
