Herceptin
It targets the HER2 protein, which is overexpressed in some cancer cells, and can help slow or stop the growth of these tumors.
Herceptin is often used in combination with chemotherapy or other cancer treatments.
Researchers can use PubCompare.ai to optimize their Hercepting research by locating relevant protocols from literature, preprints, and patents, and leveraging AI-driven comparisons to identify the best protocols and products.
This can enhance reproducibility and accuracy, streamlining the research process.

Roche), bevacizumab (Avastin, Roche), and ado-trastuzumab emtansine
(T-DM1, Kadcyla, Roche) were obtained from the University of Michigan
pharmacy. Alexa Fluor 680 NHS Ester (AF680, ThermoFisher Scientific)
and IRDye800CW (800CW, LI-COR) were conjugated to each antibody following
the manufacturers’ instructions as previously described.18 (link),27 (link) Briefly, dyes were reacted at an antibody concentration of 2 mg/mL
in PBS with 10% sodium bicarbonate (v/v) for 2 h at 25 °C and
then purified using Biogel P-6, Fine (Bio-Rad) in
Spin-X centrifuge filter tubes (Corning).27 (link) Dye to antibody molar ratios of 3.0 and 0.5 were used to obtain
the 1.2 and 0.3 degrees of labeling, respectively. The degree of labeling
was determined by using a NanoDrop 2000c spectrophotometer (ThermoFisher
Scientific) to measure fluorophore absorption and the protein absorbance
at 280 nm, corrected for the fluorophore. The degree of labeling is
defined as the average dye to protein concentration ratio. Sample
absorption spectra are included in the
run on SDS-PAGE and scanned on an Odyssey CLx to ensure all free dye
was removed (
were performed as previously described3 (link) using HCC1954 cells. Briefly, titrations of unlabeled antibody and
antibody–dye conjugates were incubated with 50,000 HCC1954
cells on ice for 3 h and washed. After the primary incubation, cells
were further incubated with antihuman IgG Fc-AlexaFluor488 at 40 nM
for 30 min on ice, washed, and subsequently run on an Attune Focusing
Cytometer (Applied Biosystems). Kd was
estimated using PRISM and is reported as Kd ± standard error.

To a mixture of 2.0 mL of 10 mg/ml Herceptin in pH 6.0˜8.0, were added of 0.70˜2.0 mL PBS buffer of 100 mM NaH2PO4, pH 6.5˜8.5 buffers, TCEP (14-35 μL, 20 mM in water) and the compounds 128, 132, 437, 481, 495, 528, 629, 633, 641, 645, 649, 654, 659, 663, 673, 709, 712, 166a, 719, 720 and 723 (14-28 μL, 20 mM in DMA independently, followed by addition of 4-(azidomethyl)benzoic acid (14-50 μL, 20 mM in pH 7.5, PBS buffer). The mixture was incubated at RT for 4˜18 h, then DHAA (135 μL, 50 mM) was added in. After continuous incubation at RT overnight, the mixture was purified on G-25 column eluted with 100 mM NaH2PO4, 50 mM NaCl pH 6.0˜7.5 buffer to afford 12.2˜18.6 mg of the conjugate compounds C-128, C-132, C-437, C-481, C-495, C-528, C-629, C-633, C-641, C-644, C-645, C-649, C-654, C-659, C-663, C-673, C-709, C-712, C-166a, C-719, C-720 and C-723, (80%-93% yield) accordingly in 13.4˜15.8 ml of the NaH2PO4 buffer. The drug/antibody ratio (DAR) was 3.4˜3.9 for the conjugates, wherein DAR was determined via UPLC-QTOF mass spectrum. It was 94-99% monomer analyzed by SEC HPLC (Tosoh Bioscience, Tskgel G3000SW, 7.8 mm ID×30 cm, 0.5 ml/min, 100 min) and a single band measured by SDS-PAGE gel.
(Herceptin, Roche), and pembrolizumab (Keytruda, Merck) were obtained
from their manufacturers. Glycan remodeling was performed by treatment
of trastuzumab with TransGLYCIT (Genovis, Lund, Sweden) according
to the producer specifications with and without the presence of a
fucosidase. For middle-level analysis, enzymatic digestion was performed
by incubation of one unit of the IdeS enzyme (FabRICATOR, Genovis,
Lund, Sweden) per microgram of mAb at 37 °C for 60 min. Prior
to further analysis, the samples were buffer exchanged to 50 mM ammonium
acetate using 10 kDa Vivaspin 500 filters (Sartorius, Göttingen,
Germany) with an end concentration of 2 mg/mL.
