An overview of cytokines and chemokines for researchers. Covers major families (interleukins, TNF superfamily, interferons, chemokines, growth factors), their roles in immune signaling, and the research tools used to study them including recombinant proteins, antibodies, and ELISA kits.

A practical guide to blocking and permeabilization for immunoassays. Covers blocking agents (BSA, normal serum, casein, commercial blockers), permeabilization methods (Triton X-100, saponin, methanol, digitonin), application-specific recommendations, and troubleshooting non-specific background.

A practical guide to optimizing antibody dilutions across applications. Covers why titration matters, starting dilution recommendations for WB, IHC, IF, ELISA, and flow cytometry, how to perform a titration experiment, and common mistakes that lead to weak signal or high background.

An introduction to surface plasmon resonance (SPR) and biolayer interferometry (BLI) for measuring antibody binding kinetics. Covers how each technology works, key parameters (KD, kon, koff), experimental design, and when to use SPR vs. BLI in antibody development and quality control.

A practical guide to isotype controls in flow cytometry. Covers what isotype controls measure, how they differ from FMO controls, when they are appropriate, common misuses, and recommendations for proper gating strategies in multicolor flow cytometry panels.

An overview of stable cell line development for recombinant protein and antibody production. Covers the workflow from gene construct design through transfection, selection, single-cell cloning, and scale-up, with practical tips on host cell selection, expression vector design, and screening strategies.
