TL1A/TNFSF15 Protein, Human

Customer Review

Based on 1 Customer Validation

TL1A/TNFSF15 Protein, the receptor for TNFRSF25 and TNFRSF6B, activates NF-kappa-B and promotes caspase activation, leading to apoptosis. It also inhibits vascular endothelial growth and angiogenesis in vitro. Operating as a homotrimer, it plays a crucial role in diverse cellular processes, including immune response and apoptosis regulation. TL1A/TNFSF15 Protein, Human is the recombinant human-derived TL1A/TNFSF15 protein, expressed by E. coli , with tag free.

Description

TL1A/TNFSF15 Protein, the receptor for TNFRSF25 and TNFRSF6B, activates NF-kappa-B and promotes caspase activation, leading to apoptosis. It also inhibits vascular endothelial growth and angiogenesis in vitro. Operating as a homotrimer, it plays a crucial role in diverse cellular processes, including immune response and apoptosis regulation. TL1A/TNFSF15 Protein, Human is the recombinant human-derived TL1A/TNFSF15 protein, expressed by E. coli , with tag free.

Background

TL1A/TNFSF15 Protein acts as the receptor for TNFRSF25 and TNFRSF6B, facilitating the activation of NF-kappa-B and promoting the activation of caspases, leading to apoptosis. Additionally, it exhibits inhibitory effects on vascular endothelial growth and angiogenesis in vitro. The protein functions as a homotrimer, underscoring its role in diverse cellular processes, including immune response and apoptosis regulation.

Verified Bioactivity

1. Measured by its ability to induce apoptosis of TF-1 human erythroleukemic cells. The ED50 for this effect is 3-15 ng/mL.
2. Loaded Tulisokibart (HY-P990007) on AHC2 biosensor, can bind TL1A/TNFSF15 Protein, Human with an affinity constant of 3.693E-10 M as determined in BLI assay.

Product Properties

Appearance

Lyophilized powder

Formulation

1.Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, pH 8.0.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.
Please refer to the lot-specific COA for specific buffer information.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
