Antibody Link doesnt exists for many proteins

For many proteins, there is no corresponding page in Protein Atlas. Have to check this

Example:

https://cd-code.org/protein/Q7T226 => https://www.proteinatlas.org/Q7T226-unknown/antibody

https://cd-code.org/protein/Q5A8T7 => https://www.proteinatlas.org/Q5A8T7-unknown/antibody
