CHRNA1 Protein, Human (His-Trx)

Cat. No.: HY-P72140
COA Handling Instructions

The CHRNA1 Protein undergoes a substantial conformational shift upon acetylcholine binding, influencing all subunits and leading to the activation of an ion-conducting channel. Yet, the acetylcholine receptor alpha subunit of CHRNA1 can be non-functional in certain cases, underscoring the need to comprehend the factors governing its functionality and integration into fully operational acetylcholine-gated cation-selective channels. CHRNA1 Protein, Human (His-Trx) is the recombinant human-derived CHRNA1 protein, expressed by E. coli , with N-Trx, N-6*His labeled tag. The total length of CHRNA1 Protein, Human (His-Trx) is 235 a.a., with molecular weight of ~44.1 kDa.

Description

The CHRNA1 Protein undergoes a substantial conformational shift upon acetylcholine binding, influencing all subunits and leading to the activation of an ion-conducting channel.

Background

Upon binding with acetylcholine, the CHRNA1 protein undergoes a significant conformational shift that impacts all subunits, resulting in the opening of an ion-conducting channel across the plasma membrane. However, in some instances, the acetylcholine receptor alpha subunit of CHRNA1 may be non-functional and not integrated into fully operational acetylcholine-gated cation-selective channels, emphasizing the importance of understanding the factors that regulate its functionality and incorporation into the functional receptor complex.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

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)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

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

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