C7/Complement component C7 Protein, Human (HEK293, C-10*His)

C7, also known as complement component C7 protein, is a key component of the membrane attack complex (MAC) and plays a key role in innate and adaptive immune responses. As a component of MAC, C7 actively participates in the formation of target cell plasma membrane pores. C7/Complement component C7 Protein, Human (HEK293, C-10*His) is the recombinant human-derived C7/Complement component C7 protein, expressed by HEK293, with C-10*His labeled tag.

Complement component C7 is an integral part of the membrane attack complex (MAC), a crucial effector in the innate and adaptive immune responses. The MAC plays a pivotal role by forming pores in the plasma membrane of target cells, leading to cell lysis and destruction. C7 functions as a membrane anchor in this process, and it can exist as a monomer or dimer, with the potential to form multimeric rosettes when part of the C5b-7 complex. MAC assembly begins with the proteolytic cleavage of C5 into C5a and C5b, and subsequently, C5b binds sequentially to C6, C7, C8, and multiple copies of the pore-forming subunit C9. This orchestrated sequence highlights the essential role of C7 in the assembly of MAC, contributing to the immune system's ability to eliminate target cells.

Approximately 95-110 kDa due to the glycosylation.

• 
  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, 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 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.
