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

Customer Review

Based on 1 Customer Validation

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.

Description

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.

Background

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.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 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
