Summary: Isolation of clonal cells from a single colony is an essential step in the process of obtaining pure populations of stably-transfected clones after gene transfer and the subsequent drug selection. In the present study, a novel, simple, and non-invasive technique for the isolation of cells from single colonies using a disposable pipette tip was developed.
Dose: A toxin-based, drug-free selection system involving IB4-SAP was employed in the present study.

IT-10: IB4-SAP; IT-11: SSP-SAP
Objective: To evaluate the hypothesis that hyperalgesia and priming induced by opioids are mediated by similar nociceptor mechanisms.
Summary: Treatment with isolectin B4 (IB4)-saporin or SSP-SAP (which deplete IB4+ and peptidergic nociceptors, respectively), or their combination, prevented systemic LDM-induced hyperalgesia, but not priming. HDM-induced priming, but not analgesia, was markedly attenuated in both saporin-treated groups.
Dose: IB4-SAP was diluted in saline and a dose of 3.2 μg in a volume of 20 μl administered intrathecally. SSP-SAP was diluted in saline and a dose of 100 ng in a volume of 20 μl was administered intrathecally.

Objective: To determine the role of non-peptidergic nociceptors in mediating mechanical inflammatory hypersensitivity in mice.
Summary: rIB4-SAP oblates non-peptidergic neurons as displayed by the decrease of purinoceptor 3. The depletion of these neurons inhibited the mechanical inflammatory sensitivity induced by GDMF and carrageenan, but not by other expected factors such as nerve growth factor implying the role of this subset of neurons to be one of mediation as opposed to direct nociception.
Dose: IB4-SAP (0.16–3.2 μg/5 μl, i.t.), unconjugated Saporin (as control, 1.8 μg/5 μl, i.t.), or saline (vehicle, 5 μl/i.t.) were injected into the subarachnoid space on the midline between the L5 and L6 vertebrae.

Objective: To evaluate priming, at both nociceptor terminals, the effect of local administration of agents that reverse type I (protein translation) or type II [combination of Src and mitogen-activated protein kinase (MAPK)] priming.
Summary: Fentanyl, acting at the -opioid receptor (MOR), induces hyperalgesia and hyperalgesic priming at both the central and peripheral terminal of nociceptors and this is mediated by endoplasmic reticulum Ca2 signaling. Priming in the central terminal is type II, whereas that in the peripheral terminal is type I. Our findings may provide useful information for the design of drugs with improved therapeutic profiles, selectively disrupting individual MOR signaling pathways, to maintain an adequate long-lasting control of pain.
Dose: IB4-SAP was diluted in saline and a dose of 3.2 μg in a volume of 20 μl and administered intrathecally 14 d before experiments.

Objective: To study the role of the cognate hyaluronan receptor, CD44, signaling in anti-hyperalgesia induced by high molecular weight hyaluronan (HMWH).
Summary: These results demonstrate the central role of CD44 signaling in HMWH-induced anti-hyperalgesia, and establish it as a therapeutic target against inflammatory and neuropathic pain.
Dose: Both IB4-SAP and SSP-SAP were diluted in saline to doses previously shown to deplete nonpeptidergic (3.2 mcg/rat for IB4-SAP) and peptidergic (100 ng/rat for SSP-SAP) fibers. The toxins were administered intrathecally, in a volume of 20 mcl, 14 d before intradermal injection of LMWH on the dorsum of the hindpaw. Treatment with either conjugate, or a combination of the two, did not significantly affect mechanical nociceptive threshold.

Objective: Most genome editing systems employ transient treatment with selective drugs such as puromycin to obtain the desired genome-edited cells, which often allows some untransfected cells to survive and decreases the efficiency of generating genome-edited cells. The authors developed a novel targeted toxin-based drug-free selection system for the enrichment of genome-edited cells.
Summary: Results indicate that a combination of the CRISPR/Cas9 system and targeted toxin technology using IB4-SAP allows efficient enrichment of genome-edited clones, particularly bi-allelic KO clones.
Dose: Cells were trypsinized 3 days after transfection and approximately 80% were incubated for 30 min at 37°C in a solution (25 mcL) containing 0.5–1.0 mcg IB4-SAP.

Objective: To define a novel preclinical measure of movement-induced breakthrough pain (BTP) that is observed in the presence of morphine controlling ongoing pain.
Summary: Novel compounds targeting IB4-binding nociceptors may improve pain management for cancer pain patients and other patient populations suffering from BTP that is inadequately treated by currently available medications.
Dose: To determine the effect of eliminating input from IB4-binding fibers, separate groups of rats received spinal administration of IB4-SAP or the control, Blank-SAP (3.2 mcg/20 mcl saline) followed by a 10 mcl flush of saline. Movement of an air bubble placed between drug solution and saline was used to monitor progress of the injection.
