    DSP Crosslinker purchased from MedChemExpress. Usage Cited in: bioRxiv. 2025 Oct 28.

    Co-immunoprecipitation of DOR and CNIH1 in DOR-RUSH HeLa cells at 0, 1, and 24 h after biotin addition using GFP-Trap beads. Interaction was detected in the presence of the DSP crosslinker (2 mM, 2 h), tubulin serves as a negative control. Quantification of CNIH1 co-precipitation signals at different time points is shown normalized to the 0 h time point. Significance was determined by one sample t-test. *, P < 0.05.

    DSP Crosslinker purchased from MedChemExpress. Usage Cited in: BMC Biol. 2021 Sep 7;19(1):194.  [Abstract]

    Effect of the co-expression of KDEL-cargo (hGHGFP-myc-KDEL) on KDELR1-mCherry co-immunoprecipitation in HeLa cells. HeLa cells co-transfected KDELR1-mCherry with hGH-GFP-myc or hGH-GFPmyc-KDEL were firstly treated with DSP crosslinker (2 mM) in PBS at 37 °C for 30 min. Cells were lysed and the extracts were immunoprecipitated with anti-RFP agarose beads.

    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    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (6.18 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

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

      Solubility: ≥ 2.5 mg/mL (6.18 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

    The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).
    Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.
     If the continuous dosing period exceeds half a month, please choose this protocol carefully.
    Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

    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.
