Source. Mouse. Specificity. This monoclonal antibody was raised against purified human C4. It is specific for an antigen expressed on the C4c domain of C4 and therefore reactive to C4 and all C4c-containing fragments of C4. Storage. Short term (30 days) 4˚C. Long term at or below -20˚C.

Recognition causes activation of proteolytic enzyme cascades, resulting in cleavage of the complement proteins C3, C4, and C5. Fragments of these proteins have important effector functions through binding to host cell receptors and pathogen surfaces ( 1 ). In the lectin pathway of complement, four pattern recognition molecules, mannan-binding.

Of note, the levels of C4 in CTRL MRL mouse serum were 16-fold lower than those measured in wildtype CTRL B6 mice or in KO B6 mice ( P < 0.001). In CTRL MRL mice, the serum C4 levels rise four-fold from 3 weeks of age to 8 weeks of age and then remain unchanged until at least 20 weeks of age.

Diagnosis is based on antigenic assays of total or free plasma protein S (free protein S is the form unbound to the protein S carrier molecule, C4-binding protein). Protein S activity can also be measured, but the assay is technically difficult and is associated with a high false-positive rate (10 to 15%) so more reproducible antigen assays are.

A, binding to the surface of a pathogen induces autoactivation of MBP·MASP-2, exposing accessory C4-binding sites on the MASP and leading to recruitment of C4. B, MASP-2 cleaves C4. Anaphylatoxin C4a is released, whereas interactions between the MASP and the C4b fragment lead to covalent attachment of C4b proximal to the activating lectin.

Fusion proteins comprising this antigen fused to the oligomerization domain of the murine complement inhibitor C4-binding protein (C4bp) and a series of homologues have been produced. These C4bp domains acted as adjuvants for the fused antigen; the MSP1(19)-murine C4bp fusion protein induced protective immunity in BALB/c mice.

The gamma-domain and the L chain constitute the catalytic site of C1s to activate C4 to C4b and can be replaced by newly coming C4. The catalytic site for C4 of C1s has been presumed to consist of a C4-binding domain and a proteolytic domain. A mAb to C1s, M81, blocked C4 activation and C4 binding to C1s. M81 recognized the H chain of C1s. Using M81 as a probe, we tried to define C4-binding.

Complement C4, a key molecule in the complement system that is one of chief constituents of innate immunity for immediate recognition and elimination of invading microbes, plays an essential role for the functions of both classical (CP) and lectin (LP) complement pathways. Complement C4 is the most polymorphic protein in complement system.

We reported recently that Arabidopsis ACYL-COA-BINDING PROTEIN1 (ACBP1) modulates sterol synthesis via protein-protein interaction with STEROL C4-METHYL OXIDASE1-1 (SMO1-1). Herein, ACBP1 was demonstrated to co-express and interact with SMO1-2 by yeast two-hybrid, co-localization, pull-down, co-immunoprecipitation and β-glucuronidase assays.

Good morning, afternoon, or evening, depending on when you're reading this. In the area with the two floor fans and the doorway blocked by lasers (az_c4_1), I seemed to have hit not just a snag, but a brick wall. I couldn't find a way past the laser beams, so I had to look up a video walkthrough. Sure enough, I found out that I needed a metal barrel to progress through the beams. However, not.

Labcorp test details for C4-binding Protein. In blood, PS exists in a free and bound state. Sixty percent to 70% of plasma protein S circulates complexed to C4b-binding protein (C4bBP), a 570 kilodalton complement system regulator. 6 The remaining protein S, called free PS, in molar excess to C4bBP, is the functionally active form of PS. Acquired protein S deficiency may be, theoretically, the.
