Human SCNN1G/ENaC-γ ELISA Kit — Application Scenarios for Hypertension, Kidney, and Airway Research

SCNN1G/ENaC-γ: The Gatekeeper of Epithelial Sodium Balance

The amiloride-sensitive sodium channel (ENaC) is a trimeric complex (αβγ) critical for epithelial fluid and electrolyte homeostasis — a focus in cystic fibrosis, hypertension, and renal salt handling[reference:69]. Among its subunits, the γ subunit (SCNN1G) stands out for its non-redundant role in channel gating and tissue-specific expression (e.g., lung epithelia, distal nephron)[reference:70]. The Human Amiloride-Sensitive Sodium Channel Subunit Gamma (SCNN1G) ELISA Kit (KTE60735) from Abbkine redefines how researchers quantify this elusive ion channel subunit[reference:71].

Hypertension and Liddle Syndrome Research

SCNN1G carries a critical conserved PY motif whose disruption is the molecular signature of Liddle syndrome (MIM:177200): early-onset hypertension, hypokalemic metabolic alkalosis, and a kidney that simply refuses to stop pulling Na⁺ back from the urine[reference:72][reference:73]. Hypertension researchers use this kit to:

• Quantify SCNN1G in renal tissue lysates and serum
• Study ENaC subunit stoichiometry in salt-sensitive hypertension
• Investigate NEDD4-2/NEDD4L-mediated ubiquitylation and ENaC trafficking[reference:74]
• Monitor SCNN1G as a biomarker for Liddle syndrome and related disorders

The kit detects SCNN1G as low as 0.021 ng/mL in serum and 0.034 ng/mL in BALF[reference:75], with a dynamic range of 0.021–4 ng/mL[reference:76] — covering physiological (renal collecting duct) to pathological (CF lung) levels.

Cystic Fibrosis and Airway Research

In cystic fibrosis, hyperactive ENaC leads to ASL dehydration → mucus stasis → infection[reference:77]. SCNN1G's extracellular loops are sites of proteolytic "activation cleavage" (e.g., by furin, prostasin, cathepsin D) that lock ENaC into a high- Po state[reference:78]. Airway researchers use this kit to:

• Quantify SCNN1G in bronchial brushings and BALF from CF patients
• Monitor ENaC activation in CFTR-deficient airway cells (up to 4-fold vs. wild-type)[reference:79]
• Study SCNN1G proteolytic processing and channel gating
• Investigate ENaC-targeted therapies for CF airway disease

Generic ELISA kits fare little better: polyclonal antibodies often cross-react with SCNN1A/B due to shared structural motifs[reference:80]. A 2023 survey of 50 CF research labs revealed that 68% abandoned ELISA for SCNN1G quantification due to "unacceptable false positives"[reference:81]. The KTE60735 solves this with two mouse monoclonal antibodies — one targeting the N-terminal extracellular domain (residues 35–62, <3% homology to SCNN1A/B) and another against the C-terminal cytoplasmic tail (residues 580–605) — slashing cross-reactivity to <1% with related subunits[reference:82].

Kidney Research and Renal Salt Handling

ENaC-γ protein levels are the proximal readout of sodium-homeostasis control across the distal nephron[reference:83]. Kidney researchers use this kit to:

• Quantify SCNN1G in renal tissue lysates and urine
• Study aldosterone-mediated ENaC regulation in kidney disease
• Investigate SCNN1G as a biomarker for salt-sensitive hypertension and chronic kidney disease
