製品説明

AChRα(97-116) is a synthetic peptide corresponding to the 97-116 region of the rat acetylcholine receptor α-subunit, and also an inducer of autoimmune diseases. AChRα(97-116) can be used in studies related to experimental autoimmune myasthenia gravis[1][2][3].

体外実験

AChRα(97-116) (10 μg/mL; 72 h) does not induce significant proliferation of lymphocytes harvested from MBP68-86-immunized Lewis rats[1].
AChRα(97-116) (10 μg/mL; 48 h) maintains the antigen-specific immune cell phenotype responsive to dopaminergic modulation in recall-stimulated EAMG rat-derived CD4+ T cells and B220+ B cells[2].
AChRα(97-116) (2 μg/mL; overnight at 4 °C) effectively detects elevated AChR-specific antibody levels in EAMG rat serum and dopamine-stimulated EAMG rat splenocyte supernatants[2].
AChRα(97-116) (10 μg/mL; 24 h pre-incubation + 24 h co-culture) stimulates CD4+ T cells from EAMG rats to differentiate into AChR-specific Tfh cells at a 3-4-fold higher ratio than in control rats, and these Tfh cells promote increased IgG2b-secreting B cell percentages and anti-AChR antibody production in co-cultures with EAMG-derived B cells[3].
AChRα(97-116) (10 μg/mL; 72 h) stimulates lymph node-derived mononuclear cells from EAMG rats to produce elevated percentages of CD4+CXCR5+ and CD4+ICOS+ pre-Tfh cells following 72 h of incubation[3].
AChRα(97-116) (2 μg/mL; overnight at 4°C) coated on ELISA plates enables detection of significantly elevated anti-AChR antibody levels in serum from EAMG rats across multiple time points and dilutions compared to control rats[3].

体内実験

Immunization with AChRα(97-116) (50 μg/rat; tail root injection; two doses (first with Mycobacterium tuberculosis-containing emulsion, second on day 30 without Mycobacterium tuberculosis)) induces experimental autoimmune myasthenia gravis in female Lewis rats, characterized by increased clinical scores, reduced body weight, impaired neuromuscular junctions, and elevated AChR-specific antibodies[2].
Immunization with AChRα(97-116) (50 μg; subcutaneous injection; day 0 and day 30) induces experimental autoimmune myasthenia gravis in Lewis rats with >85% efficiency, driving elevated anti-AChR antibody production, reduced muscle AChR clusters, and expansion of AChR-specific pre-Tfh and mature Tfh cells that promote germinal center formation and B cell antibody secretion[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Lewis rats (female, 6-8 weeks old, 140-160 g, immunization-induced experimental autoimmune myasthenia gravis)[2]
Dosage: 50 μg/rat
Administration: tail root injection; two doses (first with Mycobacterium tuberculosis-containing emulsion, second on day 30 without Mycobacterium tuberculosis)
Result: Induced a significant increase in clinical scores from day 40 onward.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.22 mg/mL (0.99 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.22 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.2 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.22 mg/mL (0.99 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.22 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.2 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
