In Vivo Antibodies

Q: How is an in vivo antibody different from standard lab grade?

In vivo products are azide-free, low endotoxin, sterile-filtered and aggregation-controlled, with carrier-free buffers and lot-level QC tailored to animal studies.

Q: Should I choose IgG or F(ab')2?

Use IgG for Fc effector functions (depletion/engagement); use F(ab')2 when avoiding FcγR interactions is important.

Q: Recommended endotoxin level?

Select low-endotoxin lots per protocol and record values from the lot-specific CoA; control endotoxin alongside dose and route.

Q: Can these be used in humans?

No. All products are for Research Use Only (RUO) and not intended for diagnostic or therapeutic use.

Q: What is InVivo Plus?

Selection & Handling Guide

Function: Select blocking, depleting, or neutralizing based on target and desired MoA.
Format: Choose IgG for Fc-mediated effects (ADCC/CDC); F(ab')2 to eliminate FcγR binding.
Dosing: Follow mg/kg guidelines from literature; common routes: i.p., i.v., s.c.
QC Review: Check lot CoA for endotoxin, purity, and sterility before use.
Controls: Always include matched isotype and vehicle controls.
