GAD1/GAD67 Protein, Human (sf9, His)

Customer Review

Based on 1 Customer Validation

The GAD1/GAD67 protein utilizes pyridoxal 5'-phosphate as a cofactor and acts as a catalyst in the synthesis of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). GAD1 plays a key role in the conversion of glutamate to GABA, a key neurotransmitter involved in regulating neuronal excitability. GAD1/GAD67 Protein, Human (sf9, His) is the recombinant human-derived GAD1/GAD67 protein, expressed by Sf9 insect cells , with C-His labeled tag.

Biological Activity

Description

The GAD1/GAD67 protein utilizes pyridoxal 5'-phosphate as a cofactor and acts as a catalyst in the synthesis of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). GAD1 plays a key role in the conversion of glutamate to GABA, a key neurotransmitter involved in regulating neuronal excitability.

Background

Glutamate Decarboxylase 1 (GAD1), also known as GAD67, is an enzyme that plays a pivotal role in neurotransmission by catalyzing the synthesis of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). GAD1 utilizes pyridoxal 5'-phosphate as a cofactor in the decarboxylation of glutamate to form GABA, a crucial neurotransmitter that regulates neuronal excitability in the central nervous system. The balanced production of GABA by GAD1 is essential for maintaining the inhibitory-excitatory balance in neural circuits and is implicated in various physiological and pathological conditions of the nervous system.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4, 8% trehalose.

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

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
