To examine the co-distribution of two (or more) different antigens in the same sample, use a double immunofluorescence procedure. This can be performed either simultaneously (in a mixture) or sequentially (one antigen after another). Ensure you have antibodies for different species and their corresponding secondary antibodies.
Immunofluorescence (IF) combines the use of antibodies with fluorescence imaging techniques to visualize target proteins and other biomolecules within fixed cell or tissue samples. This process can reveal the localization, relative expression, and even activation states of target proteins.
An introduction to Performing Immunofluorescence Staining
Immunofluorescence (IF) is a technique that permits visualization of virtually many components in any given tissue or cell type. This broad capability is achieved through combinations of specific antibodies tagged with fluorophores.

Immunofluorescence General Protocol - usbio.net
Immunofluorescence is a technique that allows the visualization of a specific protein or antigen in cells or tissue sections by binding a specific antibody chemically conjugated with a fluorescent dye such as fluorescein isothiocyanate (FITC).

Cells are plated at an appropriate density and allowed to attach to the slide or dish (ex. 30,000 cells/chamber in a 8-chamber slide). Cells are usually plated one day prior to staining in order to achieve 60-80% confluency. Note: optimal fixation (both reagent and time) depends on the antigen of interest and must be optimized.
optimize the best condition depending on the samples, target protein and the used antibodies. Please refer the antibody datasheet or references for the suitable conditions for sample preparation, ------------------------ 2.4 g. on to 7.2 by adding 5N HCl (approx. 5. hem for overnight or 2-3 days until the cells reach 50-70% conf.
