Flow Cytometry

Flow Cytometry Cell Surface Staining Protocol

Cell surface staining specifically targets proteins expressed on the cell membrane using fluorescently labeled antibodies, enabling identification and quantification of distinct cell populations.

Flow Cytometry Intracellular Cytokine Staining Protocol

Intracellular cytokine staining (ICS) is a flow cytometry technique using fixation and permeabilization to detect and quantify cytokines produced within cells after cell stimulation.

ELISA

Direct ELISA Protocol Using Immobilized Recombinant Proteins

The direct ELISA, one of the simplest forms of ELISA, involves immobilizing the antigen directly onto the plate and then detecting it with an enzyme-conjugated antibody specific to the antigen.

Activation

In Vitro Human T Cell Activation Using anti-CD3/anti-CD28 Antibodies

Activation of primary human T cells in vitro typically mimics physiological T-cell receptor (TCR) signaling plus co-stimulation. Engagement of CD3 provides signal 1 (TCR complex activation), while CD28 ligation supplies signal 2, promoting robust proliferation, cytokine production, and survival.

In Vitro Mouse T Cell Activation Using anti-CD3 Antibodies

Mouse T cells can be robustly activated in vitro by engaging the T-cell receptor (TCR) complex using plate-bound anti-CD3 antibodies. Unlike human systems, many standard mouse activation protocols use anti-CD3 alone (signal 1) and rely on endogenous co-stimulatory signals from APCs or added IL-2; however, you can add soluble anti-CD28 for stronger co-stimulation if desired.

Purification

IgG and Fc-Protein Purification Using Protein A Resin

This protocol describes a straightforward method for purifying IgG antibodies or Fc- tagged proteins using Protein A agarose resin through either column-based or batch binding approaches. Antibodies are captured via high-affinity Fc–Protein A interactions, washed to remove contaminants, and eluted under low-pH conditions followed by immediate neutralization to preserve antibody integrity.

6-His-Protein Purification Using Nickel Resin

This protocol describes a step-by-step method for purifying His-tagged proteins using Nickel affinity resin through either column-based or batch binding approaches. Proteins are captured via high-affinity His-Nickel interactions, washed to remove contaminants, and eluted under low-pH conditions followed by immediate neutralization to preserve protein integrity.

DYKDDDDK-Protein Purification Using 1002AH1 Resin

This protocol describes the purification of DYKDDDDK (FLAG)-tagged proteins using 1002AH1 antibody-based affinity resin, enabling highly specific capture under native conditions. Bound proteins are recovered using DYKDDDDK peptide or low pH elution, providing flexibility for maintaining protein structure and function.

Western Blot

Western Blot Protocol (Immunoblotting)

This optimized Western blot workflow integrates pre-transfer gel validation using BlinkBlue staining to improve experimental confidence and reproducibility. Incorporating rapid QC steps alongside standardized antibody and transfer conditions ensures consistent, high-quality protein detection.
