Non-cleavable Linker |
The crosslinker Sulfo-SMCC consists of a maleimide and an N-hydroxysuccinimide ester group to bind to sulfhydryl groups and primary amines, respectively. Sulfo-SMCC inhibits the end-to-end annealing of stabilized Microtubules (MTs). MTs are treated with 250 μM Sulfo-SMCC, and imaged after incubation for 0 h, 6 h, and 24 h. MTs treated with Sulfo-SMCC shows a constant mean length, independent of the incubation time[1].

FLT3L-based drug conjugate effectively targets chemoresistant leukemia stem cells in acute myeloid leukemia. [Abstract]2025 Sep 19:102365. PMID: 40975063

SDS-PAGE analysis of FL-Fc, FL-Fc-SMCC, and FL-Fc-DM1 under reducing and non-reducing conditions. Lanes 1 and 4: rhFL-Fc; lanes 2 and 5: FL-Fc-SMCC; lanes 3 and 6: FL-Fc-DM1.FL-Fc (1 mg/mL) and DM1 were conjugated using the crosslinker Sulfo-SMCC. FL-Fc was mixed with Sulfo-SMCC at a 1:15 molar ratio and incubated for 0.5 h. The resulting FL-Fc-SMCC was buffer-exchanged into PE buffer (80 nM sodium phosphate, pH 6.0, 1 mM EDTA) by ultrafiltration (10 kDa cutoff). DM1 (10 mM) was then added at a 15:1 molar ratio to FL-Fc-SMCC and reacted for 1 h. Unconjugated DM1 was removed by ultrafiltration (10 kDa cutoff), and the final conjugate FL-Fc-DM1 was analyzed by SDS-PAGE.

SDS-PAGE result of SCF and DM1 conjugation product. Lane 1: protein marker; lane 2: SCF and DM1 conjugation product; lane 3: rhSCF. rhSCF was conjugated with DM1 via the Sulfo-SMCC (SMCC) chemical linker (10 mM; the molar ratio of Sulfo-SMCC to rhSCF (1 mg/mL) was 20:1; incubation for 1 h). When SCF-SMCC reacted with DM1 (10 mM), 10% DMA was added to prevent precipitation of DM1 in the aqueous system, while denaturation of rhSCF caused by DMA was minimized. The final reaction product SCF-DM1 was a mixture with a higher molecular weight than rhSCF.

LC–MS result of SCF and DM1 conjugation product. + X DM1 means one molecule of SCF was conjugated with X molecule(s) of DM1, + 1 SMCC means one molecule of SCF was conjugated with 1 molecule of SMCC. LC–MS confirmed that reaction product was nonhomogeneous, with 1–5 molecule(s) of DM1 conjugated to one molecule of rhSCF. rhSCF was conjugated with DM1 via the Sulfo-SMCC (SMCC) chemical linker (10 mM; the molar ratio of Sulfo-SMCC to rhSCF (1 mg/mL) was 20:1; incubation for 1 h).

Reducing SDS-PAGE result of FL-DM1. Lane 1: FL-DM1; Lane 2: rhFL. To primarily characterize the molecular weight of FL-DM1, an uncleavable Sulfo-SMCC sodium linker (5 mM, dissolved in ultrapure water) was used to generate the FL‑SMCC-DM1 drug conjugate. FL-SMCC-DM1 migrated at approximately 21 kDa, and one conjugated SMCC-DM1 molecule was approximately 960 Da. Therefore, an average of 2 SMCC‑DM1 molecules were conjugated to one rhFL molecule using this conjugation method.

To primarily characterize the molecular weight of FL‑DM1, an uncleavable Sulfo-SMCC sodium linker (5 mM, dissolved in ultrapure water) was used to generate the FL-SMCC-DM1 drug conjugate. Based on the results of reducing SDS‑PAGE, FL had a theoretical molecular weight of 19.1 kDa (with 3 extra amino acids at its N‑terminus and 6 histidines at its C-terminus) and yielded a single band, whereas FL-SMCC-DM1 showed a smeared band, indicating a heterogeneous mixture.

Protocol
Labeled and unlabeled porcine tubulin powders are used. Sulfo-SMCC is used. MTs are polymerized to a final concentration of 2 mg/mL in 80 mM PIPES buffer (pH 6.8) containing 10 μM taxol, 2 mM MgCl2, 0.5 mM EGTA, and 1 mM GTP. A mixture of rhodamine-labeled tubulin and unlabeled tubulin (1:5) is used in the time-dependent measurements. In these experiments, polymerized MTs are divided in 2 groups: control and Sulfo-SMCC (250 μM) treated. Both samples are imaged after diluting 1:5 and incubating for 0 h (within 45 minutes after polymerization), 6 h, and 24 h[1].
