Serpin B12 Protein, Human (HEK293, His)

Serpin B12 Protein inhibits trypsin and plasmin, excluding thrombin, coagulation factor Xa, or urokinase-type plasminogen activator. It may have a role in cell differentiation, interacting with SLFN12 in a pathway regulating differentiation, and potentially interacting with USP14. Serpin B12 Protein, Human (HEK293, His) is the recombinant human-derived Serpin B12 protein, expressed by HEK293 , with C-6*His labeled tag.

Serpin B12 protein acts as an inhibitor of trypsin and plasmin, displaying specificity by not inhibiting thrombin, coagulation factor Xa, or urokinase-type plasminogen activator. This selective inhibitory profile suggests a nuanced regulatory role in protease-mediated processes. Additionally, Serpin B12 may contribute to cell differentiation, as indicated by its interaction with SLFN12 in a pathway associated with the regulation of cell differentiation. The potential interaction with USP14 further suggests the involvement of Serpin B12 in intricate cellular processes, warranting further exploration of its multifaceted functions.

Approximately 55.0 kDa

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4 or 20mM Tris-HCl, 150mM NaCl, 10% Glycerol, pH 7.5.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

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).

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.

Room temperature in continental US; may vary elsewhere.
