Mouse CD28 ELISA Kit, Lot 21AO-546 [Cancer Immune Checkpoint Assay Kit]

CAT#: IOK-05-P457
Product Type: ELISA Kit
Target: CD28
Short Description
The kit is designed for in vitro quantitative measurement of Mouse CD28 in Plasma, Serum, Tissue Homogenate.
Description
For quantitative detection of CD28 in serum, plasma, tissue homogenates.
Applications
ELISA
Target
CD28
Reactivity
Mouse
Detection Method
Colorimetric
Method Type
Sandwich ELISA
Analytical Method
Quantitative
Sample Type
Plasma, Serum, Tissue Homogenate
Specificity
This assay has high sensitivity and excellent specificity for detection of CD28. No significant cross-reactivity or interference between CD28 and analogues was observed. Note: Limited by current skills and knowledge, it is difficult for us to complete the cross-reactivity detection between CD28 and all the analogues, therefore, cross reaction may still exist.
