Description

GAD2/GAD65 proteins are key enzymes in neurotransmitter metabolism, specifically catalyzing the production of gamma-aminobutyric acid (GABA). GABA is an important inhibitory neurotransmitter in the central nervous system, playing a key role in regulating neuronal excitability and maintaining the balance between excitation and inhibition in the brain. GAD2/GAD65 Protein, Human (sf9, GST) is the recombinant human-derived GAD2/GAD65 protein, expressed by Sf9 insect cells , with N-GST labeled tag.

Background

The GAD2, also known as GAD65 (Glutamate Decarboxylase 2), protein is an enzyme that plays a crucial role in neurotransmitter regulation by catalyzing the conversion of glutamate to gamma-aminobutyric acid (GABA). GAD2/GAD65 is a major isoform of glutamate decarboxylase, and its enzymatic activity is vital for maintaining the balance between excitatory and inhibitory neurotransmission in the central nervous system. GABA serves as the primary inhibitory neurotransmitter, and its synthesis by GAD2/GAD65 contributes to the modulation of neuronal excitability. Dysregulation of GAD2 activity has been implicated in various neurological disorders, underscoring the significance of this enzyme in neural function and highlighting its potential as a therapeutic target.

Help & FAQs
  • How should lyophilized recombinant proteins be reconstituted and stored?

    1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss. 2. Taking 10 μg as an example, first add 20 μL of reconstituted solution provided by MCE and use a pipette to gently resuspend the lyophilized protein until it is fully dissolved.. (For most proteins, the reconstitution solution we provide is sterile water. If a diluent other than water is required, it will be indicated in the product's Certificate of Analysis (COA).). 3. Add an additional 80 μL of buffer/culture medium containing carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% trehalose), and then use a pipette to gently mix until uniform. The final concentration is should not be lower than 100 μg/mL. 4. Aliquot at least 20 μL per tube. 5. After aliquoting, store it frozen at a temperature ranging from -20ºC to -80ºC, and it can be preserved for 3 to 6 months.

  • How should solution-form recombinant proteins be stored?

    1. The product can be stored in its original form and diluted as needed upon use. 2. Alternatively, dilute with a buffer/culture medium containing a carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% alginate), mix well by pipetting, and ensure that

  • Why is it necessary to add carrier proteins?

    Carrier proteins are commonly added to enhance the stability of recombinant proteins, preventing them from adhering to the walls of the container during freezing or thawing processes. Plastic tubes have a certain adsorptive capacity for proteins, which may lead to difficulty in separating the protein from the tube walls, resulting in a decrease in the actual concentration of the protein in the solution and thus affecting its activity. To minimize such losses, it is recommended to add a commonly used carrier protein solution prior to the long-term storage of recombinant protein products.

  • Carrier protein types and options?

    In cases where the carrier protein is not expected to influence the experimental outcomes, an appropriate carrier protein, such as 0.1% BSA (Bovine Serum Albumin), 5% HSA (Human Serum Albumin), 10% FBS (Fetal Bovine Serum), or 5% trehalose, can be incorpo

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
