NPTXR Protein, Human (HEK293, His)

Customer Review

Based on 1 Customer Validation

The NPTXR protein may mediate synaptic processes, suggesting its involvement in synaptic material uptake during remodeling or AMPA receptor clustering at specific excitatory synapses. These effects suggest that NPTXR dynamically regulates synaptic structure and function. NPTXR Protein, Human (HEK293, His) is the recombinant human-derived NPTXR protein, expressed by HEK293 , with N-His labeled tag.

Description

The NPTXR protein may mediate synaptic processes, suggesting its involvement in synaptic material uptake during remodeling or AMPA receptor clustering at specific excitatory synapses. These effects suggest that NPTXR dynamically regulates synaptic structure and function. NPTXR Protein, Human (HEK293, His) is the recombinant human-derived NPTXR protein, expressed by HEK293 , with N-His labeled tag.

Background

NPTXR Protein emerges as a potential mediator in synaptic processes, suggesting its involvement in either the uptake of synaptic material during synapse remodeling or the synaptic clustering of AMPA glutamate receptors at specific excitatory synapses. These roles implicate NPTXR in the dynamic regulation of synaptic structure and function. Elucidating the precise mechanisms through which NPTXR participates in synapse remodeling and AMPA receptor clustering could offer valuable insights into its contributions to synaptic plasticity and neurotransmission. Further exploration of NPTXR's functions may deepen our understanding of its specific implications in various neuronal processes and its potential significance in maintaining synaptic integrity and functionality.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4 or PBS, pH7.4, 5% Trehalose, 5% Mannitol, 0.01% Tween-80 .

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.
