ACBD3 modulates KDEL receptor interaction with PKA for its trafficking via tubulovesicular carrier. [Abstract]2021 Sep 7;19(1):194. PMID: 34493279
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.

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.
Solvent & Solubility
DMSO : 50 mg/mL (123.63 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
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.
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.
