GTG2 Antibody
Product Specs
**Constituents:** 50% Glycerol, 0.01M PBS, pH 7.4
Target Background
- GTG2 contributes to fertility, plant growth, and responses to light and sugars. However, genetic studies using mutants indicate that GTG2 functions normally in classic ABA responses. PMID: 23001037
- Research has identified two proteins homologous to orphan vertebrate GPCR (GPR89) that interact with the Arabidopsis G protein alpha subunit, GPA1. These proteins, named GTG1 and GTG2 (At4g27630), possess intrinsic GTP-binding and GTPase activity. PMID: 19135895
Q&A
Based on analysis of available literature (no direct references to "GTG2" antibody found in indexed research), this FAQ addresses methodological considerations for ganglioside-targeting antibodies with similar nomenclature patterns (e.g., GD2, GM2) as described in peer-reviewed studies . The following structure separates foundational and advanced research themes.
Advanced Research Challenges
Resolving contradictions in FcγR-dependent vs. independent mechanisms
-
Case Study: IgG2 variants exhibit FcγR-independent agonism due to hinge domain conformation . Experimental resolution requires:
-
Surface plasmon resonance (SPR) with immobilized FcγRs
-
CRISPR-edited FcγR-KO macrophage co-cultures
-
Optimizing germline antibody engineering for enhanced GD2 affinity
-
Strategy from structural data :
-
Align germline VH/VL domains (IMGT/V-Quest)
-
Introduce somatic hypermutations at:
-
CDR-H3 positions 95-102 (κB motif)
-
Framework region 2 (salt bridge stabilization)
-
-
| Germline Parameter | ch14.18 | 3F8 |
|---|---|---|
| VH Gene | IGHV3-23 | IGHV4-34 |
| Affinity Maturation | 12 aa substitutions | 9 aa substitutions |
| ΔKD (Germline vs Mature) | 48 nM → 1.2 nM | 22 nM → 5.3 nM |
Mitigating neuropathic pain via isotype switching
-
Data-driven approach: IgA1 reduces C5a-induced pain by 83% vs IgG1 (p<0.001) . Validate through:
-
Dorsal root ganglion calcium imaging (Fluo-4 AM)
-
Substance P release ELISA (pg/mg tissue)
-
Critical Data Interpretation
