Source

Bat coronavirus Anlong103 Spike Trimer Protein, His Tag (SPN-S522f) is expressed from human 293 cells (HEK293). It contains AA Asp 14 - Pro 1173 (Accession # A0A1W5YKT9 (R645A, K946P, V947P)).

Predicted N-terminus: Asp 14

Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 133.5 kDa. The protein migrates as >160 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a trimer.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in 0.1 M Sodium citrate, pH5.5 with trehalose as protectant.

Background Introduction

The spike protein of bat coronavirus Anlong103, a SARS-CoV-2–related sarbecovirus identified in bats from China’s Guizhou province, mediates viral entry by facilitating receptor attachment and membrane fusion. While closely related to other bat coronaviruses, Anlong103’s spike shows distinct structural features that may limit human ACE2 binding, yet retains conserved antigenic sites. These characteristics make it valuable for studying cross-species transmission potential and coronavirus evolution in wildlife reservoirs.
