IHC image of CSB-RA008545MA1HU diluted at 1:150 and staining in paraffin-embedded human lung tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0) . Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-human polymer IgG labeled by HRP and visualized using 0.05% DAB.

About Recombinant Antibodies

Recombinant antibodies are monoclonal antibodies whose heavy- and light-chain sequences are cloned and expressed in defined cell lines (CHO or HEK), rather than produced from a hybridoma or animal serum. Because the sequence is archived, every lot is identical, production is animal-free, and supply does not depend on a cell line or host animal — the format of choice when reproducibility and long-term availability matter most.

Choosing an antibody format: Recombinant vs Monoclonal vs Polyclonal

Recombinant antibodies sit at the reproducibility end of the spectrum. Use the table to weigh them against conventional monoclonal and polyclonal formats.

AttributePolyclonalMonoclonalRecombinant
SpecificityModerate-high - multi-epitopeHigh - single epitopeHigh - single defined epitope
Batch consistencyLow-moderateHighHighest - sequence-defined
Cross-reactivity riskHigher - multiple clonesLowLow
Animal-freeNoPartialYes - fully animal-free
Supply continuityLimited - animal & lot dependentGood - cell-line dependentExcellent - sequence archived
Best forLow-abundance / denatured targetsValidated, reproducible assaysLong-term reproducibility & supply
How to read this: choose recombinant when lot-to-lot consistency, animal-free sourcing, or guaranteed supply are priorities; a conventional monoclonal or polyclonal antibody may be more economical for routine or exploratory work. For the full decision framework, see the antibody format comparison guide.
