Description

Woodchuck secreted CTLA4, also known as Cytotoxic T-lymphocyte-associated protein 4 and CD152, with N-terminal Avi-TagTM fused to the Fc region of Human IgG1, a.a. 36-162 expressed in a HEK293 cell expression system. MW = 42 kDa (monomer). This protein runs at a higher MW by SDS-PAGE due to glycosylation.

Storage/Stability

At least 6 months at –80°C

Assay Conditions

Reaction done similar to human CTLA4:B7-1[biotin] assay kit (BPS Catalog # 72009) protocol. Buffer is PBS with 0.1% BSA. Blocking buffer is Superblock + 0.05% Tween-20. The coat protein, woodchuck CTLA4 (wCTLA4), was added ON at 4 deg (various concentrations as indicated). Binding reaction initiated with addition of woodchuck B7-1-biotin (wB7-1-biotin) for 2h at RT. Binding was detected using Strep-HRP generated luminescence.

Instructions for Use

Thaw on ice and gently mix prior to use. DO NOT VORTEX. Perform a quick spin before opening. Aliquot into small volumes and flash freeze for long term storage. Avoid multiple freeze/thaw cycles.

Shipping Temperature

-80°C

Notes

HiP™ indicates a high purity protein with ≥90% purity as measured by gel filtration.

Warnings

Avoid freeze/thaw cycles. Protein may be diluted to ≥ 100 µg/ml in PBS + glycerol and stored at -80°C.
