| ALP22609 | P98086(E23-A245) |
|
|
| The C1QA protein helps form C1, the starting component of the serum complement system . C1q binds to the zymogens C1r and C1s, resulting in C1 assembly. | |||
| ALP22614 |
Recombinant C1s/Complement component C1s Protein,Human,HEK293,C-His |
P09871(E16-D688) |
|
| C1s/Complement component C1s, a serine protease and B chain, forms C1 with C1q and C1r, initiating the classical complement pathway. Activated by C1r, C1s then activates downstream components C2 and C4, crucially driving the complement system cascade. | |||
| ALP22615 | P98086(E23-A245) |
|
|
| The C1QA protein helps form C1, the starting component of the serum complement system . C1q binds to the zymogens C1r and C1s, resulting in C1 assembly. | |||
| ALP22647 | Q8CG14(E16-D688) |
|
|
| Recombinant C1s-A subcomponent Protein, expressed in HEK293 cells with C-terminal His tag. | |||
| ALP22643 | Q8CG14(E16-D688) |
|
|
| C1s-A subcomponent protein, a serine protease, is pivotal in the classical complement system pathway. Partnering with C1q and C1r, it forms C1, initiating complement activation. Activated by C1r, C1s can subsequently trigger downstream components C2 and C4, influencing the complement system cascade. | |||
