SIRP beta 1 Protein, Human (HEK293, His)

SIRP beta 1 protein negatively regulates receptor tyrosine kinase signaling and recruits SYK for myeloid cell activation. It interacts with TYROBP as a homodimer, facilitating SYK recruitment. This intricate molecular interplay is crucial for modulating myeloid cell activation and regulating cellular signaling. SIRP beta 1 occupies a central position in protein interactions that contribute to its functional role. SIRP beta 1 Protein, Human (HEK293, His) is the recombinant human-derived SIRP beta 1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of SIRP beta 1 Protein, Human (HEK293, His) is 333 a.a., with molecular weight of 45-55 kDa.

SIRP beta 1 protein, an immunoglobulin-like cell surface receptor, plays a vital role in the negative regulation of receptor tyrosine kinase-coupled signaling processes. Additionally, it participates in the recruitment of the tyrosine kinase SYK, triggering the activation of myeloid cells when associated with TYROBP. Existing as a homodimer with disulfide linkages, SIRP beta 1 interacts specifically with TYROBP, leading to the recruitment of SYK. This intricate molecular interplay positions SIRP beta 1 at the nexus of cellular signaling regulation, highlighting its significance in modulating myeloid cell activation and the intricate network of protein interactions that contribute to its functional role.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 20 mM PB, 150 mM NaCl, pH 7.4.

<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. 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.
