in_category() and tax_query with custom post type

I’m using custom post type, that i have named “products”
For this post type i have add the custom taxonomies, that have name “products_brand”
There are two terms in it now: “natige” and “osakarovka”

For my custom post type “products” I have created a custom template, that I called single-products.php

It’s so conceived, that each taxonomy term (“natige” and “osakarovka”) must have different design.

I tried to do this with in_category() WP function, but it doesn’t work.

Please tell me, how can I write my template to do this algorithm:

if category is “natige”

elseif category is “osakarovka”

end

Here is my single-products.php code:

<?php get_header(); ?>

<div id="body">
<div class="fix">
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>


<?php   
if ( in_category(array(

                'tax_query' => array(
                    'taxonomy' => 'products_brand',
                    'field' => 'slug',
                    'terms' => 'natige'
                ),
                'post_type' => 'products',
                'posts_per_page' => 1,
