IPTG Powder Cell Culture Additive

CCM-RG-0022 is IPTG, isopropyl beta-D-1-thiogalactopyranoside, supplied as a dry powder for use as an inducer in lac and lac-derived expression systems. The source specification classifies the material as animal-origin-free and as a cell culture additive for cell-culture-related reagent workflows. It is supplied in a 1 g pack size, with a listed shelf life of 48 months when stored under the recommended conditions. For buyers consolidating research consumables, this product belongs within our cell culture reagents portfolio.

IPTG is a non-metabolized analog of allolactose used to relieve lac repressor control in compatible host systems. In practical laboratory use, it is commonly prepared as a sterile-filtered stock solution, aliquoted to reduce repeated freeze-thaw or contamination risk, and added to culture media at a concentration determined by the expression construct and host strain. Because optimal induction level depends on promoter architecture, copy number, growth temperature, induction phase, and target protein characteristics, users should qualify working concentration internally for each protocol. pH, osmolality, sterility, and endotoxin limits are not stated in the provided source specification; these attributes should therefore be confirmed against the lot documentation when they are critical to a process or assay.

• Induction of lac, tac, trc, and related promoter systems in compatible microbial expression workflows supporting upstream research and process development.
• Preparation of defined media supplements for recombinant protein expression studies where an animal-origin-free inducer is required by internal sourcing standards.
• Small-scale screening of induction timing, inducer concentration, culture temperature, and harvest point during clone or construct evaluation.
• Scale-up support for shake flask, micro-bioreactor, and bench bioreactor studies in R&D laboratories, subject to site-specific qualification.
• Analytical and assay-development workflows requiring a documented IPTG reagent for controlled induction of reporter systems or pathway components.

For procurement teams, the key ordering attributes are straightforward: CCM-RG-0022, IPTG powder, 1 g size, animal-origin-free classification, 48-month shelf life, 2 to 8 °C light-protected storage, and blue-ice shipment. The listed unit price is USD 161.11, and volume requirements can be submitted through the request a quote workflow for confirmation of availability, lead time, and multi-unit pricing.

Store unopened IPTG powder at 2 to 8 °C and protect it from light, as specified for this product. Shipment is specified on blue ice to support temperature control in transit. On receipt, verify the pack condition, label, quantity, and any lot-specific documentation before release to laboratory inventory. Once opened, handle using standard clean laboratory technique to minimize moisture uptake and contamination. If a stock solution is prepared, use validated water or buffer, filter if required by the protocol, label with concentration and preparation date, and store aliquots according to an internally approved method. Avoid unnecessary exposure to room light and repeated container opening. Users should establish local expiry after reconstitution because the 48-month shelf life applies to the supplied powder under recommended storage conditions.

CellCultureMedia supplies CCM-RG-0022 for research, cell culture, and bioprocess support use with procurement-focused documentation on request. Manufacturing and supplier controls are managed through ISO-aligned quality practices, with lot traceability maintained for order fulfillment and post-delivery support. A Certificate of Analysis can be requested where available, and buyers should review the CoA for lot-specific identity, appearance, purity or assay data, and any applicable quality attributes before use in qualified workflows. Additional documentation requests can be routed through our quality information channel. Free worldwide shipping is available for eligible shipments, with blue-ice handling applied according to the stated shipping condition.
