What are recombinant multiclonals?
Recombinant multiclonals are a mixture of recombinant antibodies co-expressed from a library of heavy and light chains. They offer several advantages including:
- The sensitivity of polyclonal antibodies by recognising multiple epitopes
- High batch-to-batch consistency and reproducibility
- Improved sensitivity and specificity
- Long-term security of supply
- Animal-free batch production

Rex1 also known as Zfp42 is a transcription factor and zinc finger protein with a mass of approximately 42 kDa. This protein is expressed mostly in embryonic stem cells and some adult stem cells. Rex1 functions by binding to DNA sequences influencing gene expression that is essential for maintaining stem cell self-renewal and pluripotency. As a result Rex1 plays an important role in regulating cellular processes related to developmental potential.
Biological function summary
Rex1 influences stem cell pluripotency and differentiation. It is part of the network of pluripotency factors along with Oct4 Sox2 and Nanog. These proteins form a regulatory circuit that maintains embryonic stem cell identity. Rex1 directly interacts with chromatin structure facilitating the accessibility of specific genes related to stem cell maintenance and identity. The expression levels of Rex1 have a significant impact on the transition between pluripotency and differentiated states within cells.
Pathways
Rex1 is involved in key signaling pathways regulating pluripotency like the LIF/STAT3 and Wnt signaling pathways. Within these pathways Rex1 collaborates with other transcription factors to promote the expression of genes required for stem cell growth and maintenance. Rex1 and Nanog work closely in these pathways to sustain the pluripotent status of stem cells by activating necessary genetic programs and preventing differentiation signals.
Rex1 has connections to certain cancers such as teratocarcinomas due to its role in maintaining pluripotency. Another protein Oct4 often has elevated levels alongside Rex1 in these cancerous cells which drives the tumor's stem-like characteristics. Rex1 levels have been associated with tumor formation and progression in some cancer types suggesting that it could be a biomarker for cancer stem cells and a potential target for therapies.
