VISTA/B7-H5 Protein, Human (HEK293, His)

カスタマーレビュー

Based on 1 Customer Validation

VISTA/B7-H5 protein, an immunoregulatory receptor, inhibits T-cell response and may regulate embryonic stem cell differentiation by inhibiting BMP4 signaling. It also stimulates MMP14-mediated MMP2 activation, suggesting a role in matrix metalloproteinase processes. These roles highlight the significance of VISTA/B7-H5 in immune regulation, embryonic development, and extracellular matrix dynamics. VISTA/B7-H5 Protein, Human (HEK293, His) is the recombinant human-derived VISTA/B7-H5 protein, expressed by HEK293 , with C-6*His labeled tag.

Product Properties

性状

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

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.

輸送条件
